Setup & Installation / Re: ArcaOS, VirtualBox, and mouse freezes
« on: February 16, 2022, 06:46:31 pm »
So when the mouse freeze occurs, have you tried running Top or the testlog program?

Of course not possible !
Keyboard uses same unify dongle as my mouse and both are unusable


(freeze seems more to be in relation with usb...)

Remy,
It certainly could be a conflict with some background process like a widget. When the mouse freezes, is the rest of the system working? Can you use the keyboard, for example? If so, can you run Top to see what activity shows up in the list?
Bennie

My keyboard works with my mouse on the same usb unify dongle.

Remy,
Under virtualbox using the VB Guest Additions, the video driver is a customized version of gengradd. Which video driver are you using? Can you switch to one of the other available drivers?
Bennie

Hi Benni,

As I wrote, I don't use VB
I directly boot into ArcaOS, no VB

It looks more like the problem is related to usb access...
but I didn't identify the real case making the freeze occur for a few seconds and difficult to reproduce due it is from time to time and sometime, nothing for a few days and then again...
I also suspected a keyboard or mouse temporary problem (like a key sending a pushed state which prevent them other keys or mouse to well works - unify keyboard and mouse in my case) and to exclude them, despite both worked well under windows, I bought a new keyboard and mouse and my first impression was, it was the culprit but after a few days, freeze occurred again making me exclude both devices from investigation...
Q: could a running daemon or widget be the culprit ?  :-\

I'm not under virtualbox (boot through airboot or direct after boot disk choice) and have from time to time mouse freeze too since I upgraded my systemto 5.0.7  (normal mouse driver)

Could it be some drivers compatibility ?

My last test:
I used my older and smaller SSD (240GiB)
- Added 3 partitions fat32 no name no letter under windows (first one was created with a 1MiB start offset  (ok, aligned))

Now booted into ArcaOS with AHCI /A:0 /P:1 /4   this SSD been at this adapter / port number  (/4 to use 56 sectors as it is written)
I could see my disk under DFSEE and the 1MiB free offet before the first partition
I opened LVM, LVM could see it with the good size value
I tried to set names and letter but LVM replied unable to update the disk ...  (The disk is seen under LVM but in fact unusable from under LVM)
Like this, partitions unusable
I deleted partition and created them using LVM (simple), partitions where created.
I check under DFSEE and none are aligned (system CCC 255 63 and logical CCC 64 32)
From my test, I do not understand what /4 parameter on AHCI  is realy supposed to do.
In all cases I tested, i never could have aligned partition on SSD usable by ArcaOS and airboot requires 63 sectors to allow its installation.

From my point of view, this is major issue to be resolved because it has lifetime issue on SSD which are more and more used in replacement of HDD.
(New SSD have a big write possibilities but when you do many write operation a day [several GiB], it is good to preserve its lifetime with correct SSD usage - and been use it correclty under linux for fstrim is welcome too to gain speed again when it drop down)

If someone is able to find the solution to correct this, I'm interested

Good to here that it works now. Interesting, thanks for the detailed info.

I guess you've used DFSee for cloning?

Ok, you've written that you've used DFSee in the other thread.

In fact, my partition aren't aligned - I used an other calculator but I didn't care this one was rounding results making me think partition are aligned (what realy corrected is the 63 sector required to install airboot and the fact that it didn't install airboot on the right disk)

Dfsee allow you to specify starting offset. About the field under DFSEE to set an offset at partition creation, it finaly trouble me because I read it is in MiB but after check, it added 1 cylinder ! (no good - may be I forgot to read something, if it was 1MiB then it would be nice but with 1 cyl, no interest)
 
I did not find how to align partition for SSD under dfsee... except to calculate all CHS, offset and partition by hand and update partition table... Very easy to make a mistake
The problem is that as soon partition are aligned, LVM information update make the disk unusable because it reduces the size to 32 sector (good to respect alignment but odd for the SSDdisk size) and than, the total disk size is reduced to a maximum of 64k cynlinders (drop from 1TB to below 70 GiB ! with my 2 first partitions left aligned 40GiB + 4GiB an,d the next unavailable to format because it is considered above maximum size)

AHCI has a 56 sectors option for alignment but this makes a small disk size too due to the 64k cyl limitation and a max head of 255. The other option would be to use higher sector size e.g. 1024 or 2048 or better when aligned 4096 (4k) but this will prevent use of airboot (63s only)

Just looked at https://www.arcanoae.com/wiki/ahci/ which talks about the various alignment bugs.
Forget the equivalent to COPY IBMS506$ con: for AHCI, could always run testlog.

I have ArcaOS 5.0.7 (the latest and of course, the latest AHCI. Alignment is not correct for SSD (it is for HDD)
I didn't test the 56 sectors to check its result. I did a test adding the adapter, port and /4 on the SSD disk and boot it.
This flag has no incident during the boot.
Will it allow correct alignment when creating volumes under LVM ? I don't know !

(Why don't they use same tricks as used by some users, add an offset of 1MB at beginning of the disk  ::) )

BTW: IIRC, you need sysinstx only when the filesystem has changed. (Not really sure, if this is correct.)

Yes, this should be the case but I've got one time partition not booting and after sysinstx it was ok.
After this error, I issued it after each time I recovered a bootable partition (it is quick to do) and seems not to provide a problems.

I have to correct my latest update about partition aligment !

Finally partition aren't aligned (I used an other calculator but this one rounded results making me think been aligned)
and It seems not possible with ArcaOS to have them aligned on SSD using default driver settings

(I checked under linux using fdisk always providing unaligned partition messages but linux is now able to mount 2 partitions of the 3). I check partition from my older SSD (a 240GB) and first partition was at the same offset  :(  x'7F' not good start offset (If you check your SSD under DFSEE and found under it that first one is at offset x'7F' then, it isn't aligned...     

Here is the SSD layout seen under windows7 (msinfo32)
Should AHCI be started with a specific parameter to force use of aligned partition on SSD, I'll check this next...
But first, I have to find out on which adapter this disk is connected to...

(As known, not aligned partition on SSD will increase write operation and this reduces SSD ifetime which is given on a number of write operation)

After SSD partition rebuild all is ok and the airbot option is back again.

Resume: Disk was unaligned but workd under ArcaOS (unaligne due to a wrong clonning operation)
After partition alignment and able to use my full 1TB, the number of sectors was set to 127 instead the more usual 63 value.
Aiboot responded with installed but in fact, it didn't install it on my current new disk but on the windows disk in my desktop (M.2 on mainboard) and havin the airboot menu at start made me think it was ok... but realy wasn't.

Not having the airboot option available was normal because the airboot wasn't physivally installed into this disk.
I saw after reboot following a remove of unnecessary disk, airboot install responsding number of sector not eqaul to 63 !
(number of sector is normaly not a restriction but for airboot, it is).

After several corrections and finaly got it working with a sector number set to 63, airboot was correctly installed on this disk (checked with dfsee) and now, the option reboot from [airboot] is available again (nothing to do with OS or xcenter install upgrade)

OCZ and G.SKILL

Now using Kingston, it works well when used as external USB disk too (low power requirement to write and start, oter SSD use more and then less but when using on USB2, power on power use is more important because it can prevent the ready state)
(lates samsung EVO or Pro are nice but QVO has shorter lifetime)

having go all SSD issue du a major error having used DFSEE to do a disk clone from HHD to SDD.
Use it only between same media type and be carreful about the disk unique id which is copied too ! (this prevents use of both disk under a same system e.g. windows)

Under desktop system:
Finally, the best option to go from a HDD to SSD is to start from new SSD, create new partion on it and set those elligible to boot from. Then, format them from a bootable system (ArcaOS, eCS) and xcopy (with required parameters) from HDD to SSD with verify. Then sysinstx.com D: (D: current new partition letter supposed to be the futur new boot C: partition) to be sure it is ok (may be a chkdsk D: /f if jfs to verify a last time that the parttion is clean but of course, it should be).

Resume: give a unused partition letter to the new one, boot on the old partition with the new disk online.
Once done all operations to make the new partition a clone from your original one, change the drive letter of the new one to the correct bootable drive letter (I used Dfsee lvm update for this) and remove the older disk before boot into new one.

Andreas,

I use DFsee (or dfsanos2 via minilvm) to create partitions. All my SSDs (including Samsung 860 EVO, 500 GB) work.

OK, but how do you know that your partition boundaries are actually aligned?

Remy's point is that unless you have that 4K alignment, it is known that the performance of your SSD is degraded given multiple memory page reads that occur otherwise (I believe, but easy to find detailed on-line explanation out there).

I do have various SSDs. Samsung Evo 840, 850, 860, Crucial, noname, even one with IDE interface, different WD drives, SanDisk.... Usually when not in a preinstalled Win system they are all partitioned with DFSee. A few with the DFSee engine included in ArcaOS installer. They all work. They all work very fast. They all work reliable as far as I can say using some of them about 10 years now. Of course some are newer so no clue if they all will work in 20 years too.

I measure transfer speed, reading/writing of small and large files and usually compare it to the at that time state of the art other OS. And I'm quite happy with the performance.

But I don't care how DFSee aligns partitions. I guess it does it right. At least in my experience it doesn't do it wrong. If I would fear about some problems with DFSee I would ask in the DFSee group. But I definitely don't complain about a problem I've never seen in any of my systems.

I already have a 64GB and a 128GB SSD out of order (end of life)

Check starting offset of your partition. If the value is a multiple of 4096 then, you are ok. (aligned)
As I can see it now on my system, dfsee put my first partition by adding 1 in the ofset field (1MiB) at 15MiB from beginning (and aligned) (note: I could get back nearly 15MiB after delete/create from end ans aligned was preserved) 
As written if not aligned, you have more write operations which isn't good for SSD (it will slowdown faster despite it could take some time and is write operation dépendant - downloads, maintenance etc...) and of course it has some impact on performance (not a lot because SSD is very fast and a litle drop into speed is very difficult to see in normal use but ujnder benchmark, you should see some. To check it, you should compare an SSD with an aligned partition and one with unaligned.

It looks I missed something under dfsee...
default setting aren't good for ssd.
I redo all partition on my SSD using dfsee and found that adding an offset of 1 (default = nothing) to the first partition starting from beginning made the trick left  CHS to xxxxx-255-s63   (required for airboot - see below)
(all partition are now aligned)
.
I tried to update my airbot and I do not why, but it wrote into my Win7 ssd disk (only for win7 and M.2 pligged on the mother board)
Now, My windows is no more able to start Airboot corrupt message.
Trying to repear it or remove is unsuccessful due to not a 63 sectors !  (I hoppe not having lost my windows, I have no backup due I only did operation on the ArcaOS disk until airboot decided to prevent me booting windows.... Have now to find how to correct MBR without partition lose  :(
First check if I'm able to get a diskimg ...

   
 

Recovered :D

Bad CHS (not S32) was set into LVM information on the disk ! I suppose it was dfsee which wrote into my windows MBR
and Airboot was in it too but corrupted and no reparable nor removable...

Action: Removed LVM information from my windows disk.
Airbot always corruped
Starting a repair of the airboot again and this time the repair was successful.
New test and windows boot again from airboot.
This made me check something else...
Back to my ArcaOS, run airboot install. It told me not installed ! (I installed it and reboot but I don't know on which disk it installed airboot)
After reboot, I check my disk mbr/lvm and I could not find the installed airboot ! Question where did it install (it looks it installed it again on my windows disk (this looks to be an error somewhere in the code because it should install on the disk (with s32) under which I run the airboot installation.

Now, I have my explanation why I no more have the [Airboot] option for reboot under xwcenter shutdown.
I think having lost about 3 year of SSD utlisation following all staff I did but now, I learned a lot and know ow to correctly use an SDD.
You too If you followed this post (in fact, very easy and this should be noted somewhere for easy reuse)
