Setup & Installation / Re: NVME Issues
« on: May 04, 2023, 03:39:41 pm »
In theory, you should be able to add the NVMe driver to the ArcaOS 5.0x installer and finish the installation.

In practice, I have not been successful. Partly, that is because I am a beta tester, and have access to the ArcaOS 5.1 beta. That installs with no issues with NVMe. So I didn't try very hard to get 5.0 to install.

What does work easily is to take an ArcaOS 5.0 installed on hard drive, add NVMe driver, and copy to an NVMe hard drive, then boot to it. I've been running NVMe for a while on my Lenovo ThinkCentre M920q (tiny form factor).

I'm new to using NVMe drives, and I bought a cheap 2 TB one, and it failed at a little over 10000 hours of use. I hope these things are reliable.

Kermit/2 for OS/2 supports DECnet in conjunction with DEC's PATHWORKS For OS/2 product version 2.3 or later. I wonder how they do it?

Setup & Installation / Re: ArcaOS 5.0.x OVA for VirtualBox
« on: April 23, 2023, 09:21:56 pm »
I tried to open the OVA on my Windows computer, but it complained about invalid value WAS in AudioAdapter/@driver attribute on line  124.

Only then did I actually read the readme, and I'm trying to open with Virtual Box 6.1.42 and it needs Virtual Box 7.0.8

I don't think its wrong for Arca Naoe to say they are working on a new operating system version, or what features it will have. But I don't want them to announce that it is nearly out. That kind of announcement is pretty discouraging to re-sellers.

By the way, I'm posting from the "mythical" 5.1. If you need GPT or UEFI, this is a good change. If you don't, ArcaOS 5.0 should be fine.

I guess it's the same with the new browser. No one knows when a stable version will come out. I love the blow-by-blow of trying to build it, and even to move to a newer version, but I don't need a prediction of when the hangs and other problems will be solved. I just need to know when to press the update button.

Just for the record, PMMail does not use EAs. Using RSync to copy the mail store does add EAs to every file.

I don't know why that would cause RSync to use more time to transfer the files.

Isn't PMMail now compiled with GCC/Libc? Libc does add EA's to everything it touches.

When I run PMMail, it creates these EA for new messages: UID, GID, MODE, INO, RDEV, GEN, FLAGS. These are exactly the ones targeted by eaclean -c.

As for networking between Warp Connect and ArcaOS, I don't think the default install will allow it. You might be able to coax Samba to using netbios over tcpip to communicate, the newer the Samba, the harder as the old netbios is very insecure. Or install the old netbios component, maybe with NAPS, which should work fine.

I can use NETBIOS between ArcaOS 5.0.7 (or even 5.1) and Warp 3 Connect, even with SAMBA running on ArcaOS.

The UUID etc being cleaned should be fine. Have to remember that symlinks and permissions are also kept in EA's. While only some things (Samba?) care about the permissions, there are lots of symlinks that are important.

The eaclean program used with the -c parameter does not clean the symlink EA. It only removes the ones listed.


This sounds very like flags needed for SAMBA or for sharing files with any multi-user system. Is there any way to test SAMBA in this case? If I got my Ubuntu system working again, could I use the Ubuntu SAMBA client to detect the difference?

I would like to see modern WiFi on ArcaOS. The WiFi needs to come on automatically. if it can't connect to the last known access point, then it needs to find one from the previously used points. If it can't find one of those, then it can allow the user to do something.

I want to see memory managed better, so that more memory is available to the system. Modern computers seen to have less memory available to OS/2 than 15 year old computers. Virtual Box offers 3.5 GB, better than any hardware ArcaOS that I have. The RAM disk in ArcaOS is admirable. I'd like to see it extended so that programs had some access to it more directly than file i/o to the RAM drive.

I'd like to see support for the laptop button features such as brightness, speaker volume, camera enable and wifi enable.

Would there be a downside to cleaning off those libc-based EA from my entire drive? If libc puts them in, there must be an advantage to having them.

Using RSync to copy the mail store does add Extended Attributes (EAs) to every file.

I don't know why that would cause RSync to use more time to transfer the files.

Rsync does not add EAs to every file when I use it. I'm pointing my rsync to an rsyncd running on the server.

Rsync is very fast, but the OS/2 code to read EAs is very slow, and apparently hogs critical system resources. My server machine appears to hang for up to 10 minutes, but it recovers and continues. This is unacceptable in a server. I need backups to work well. A recent server hard drive crash motivated me to improve my backup strategy.

But some EAs are useful to OS/2, so I want to keep some of them. eaclean gave me a way to remove the EAs that  I didn't need.

This is my call to rsync.

Code: [Select]
commandString = 'bin\rsync' /* name of the executable */,
                '--del' /* delete files on target that no longer exist on source */,
                '--ignore-errors' /* delete files even if there are I/O errors */,
                '--xattrs' /* support extended attributes */,
                '--stats' /* show statistics at end */,
                '--itemize-changes' /* what rsync is doing with each file */

What adds the UID, GID, MODE, INO, RDEV, GEN, FLAGS extended attributes? I suspect SAMBA 3.6. Maybe Dave is right that it's libc.

I keep my data on a single JFS drive, including my PMMail test mailstore, which has over 1 million messages. I back up this drive (2 TB) to several other drives on other computers using Rsync in client/server mode.

Due to a drive failure on my main computer, I had to use Rsync to transfer the entire drive, which took 30 hours. This seemed long to me, so I experimented with things and found that the PMMail mailstore was taking most of the time. Not only that, but the server was so loaded down that I could not use it.

Further experimentation showed me that it was the Extended Attribute (EA) processing that was taking so long. I used eaclean, by David Azarewicz to remove the EA from my mailstore message files and the time to transfer the mailstore using rsync changed from 9 hours to 45 minutes. The server was no longer impacted and the user interface ran normally.

You can obtain eaclean from David's Software Download Center

eaclean was able to remove unnecessary EA over one million files in a few minutes.

It looks useless to me. localtime calls DosGetTimeDate, so every call will return 12:00 Jan 1, 1970. (or maybe garbage)

I can confirm that the US Robotics USB modem works great with ArcaOS. I'm using the latest Arca Noae USB drivers.

I will also note that land lines, FAX and dial-up are now much less commonly available. I found challenges using a modem that were just me trying to remember how we used to do communications.
