Applications / BackAgain/2000 Unreliable
« on: February 15, 2019, 06:20:50 pm »
I recently returned to using OS/2 after moving to Linux 25-years ago.  I had been searching for a file-level backup solution and had purchased Sytos Plus 1.3, Sytos Premium 2.1, and Backmaster 2 from eBay to evaluate.  None of these provided a generic SCSI driver and none would backup to a JFS disk partition or SMB share without aborting.  I also evaluated NovaDisk+ 6.01, but this couldn’t restore HPFS extended attributes.  NovaBack+ 6.01 appeared to work on my Warp Server 4.52 installation, but the software would not recognize any SCSI tape devices on my ArcaOS systems.  I thought I had found a viable solution using BackAgain/2000.

Wanting to expand the size of the boot partition on my Warp Server 4.52, I stood up a second OS/2 boot partition with some free space between the partitions.  I booted to this second partition and made both a BA/2K tape backup and disk backup of my original boot partition.  Both backups were verified and only a few inconsequential files were excluded from the backups due to file locks.   I deleted and recreated an expanded boot partition, and restored the BA/2K backup from tape.  When rebooting Warp Server, I was presented with missing config.sys device driver errors and also observed missing files preventing Lan Manager from starting once booted.  I again attempted the restoration from the BA/2K disk backup with similar results.

There’s nothing worse than an unreliable backup solution.  I will be removing BA/2K from all of my systems this weekend and will continue looking for a viable tape backup solution.

I have been missing out on this little gem.  Will install this evening.  Thank you!

Utilities / Re: best process killer application

PKill.exe is included with ArcaOS. It is a command line tool, that seems to do the job well.

Thank you, I have also been looking for something to kill processes.  For fun, I just tried a "ps -ax" at an OS/2 command prompt, but no surprise, unknown command.  I see ArcaOS provides top, so I can find PIDs there.

Applications / Re: 3d launch pad
« on: January 16, 2019, 05:20:33 am »
It's a very useful application for me and very nice of Andrey to release this for all to use.  I'm used to dual monitors, but limited to a single monitor running OS/2 via a VM.   3d launch pad reduces the effort/clicks to launch frequently used applications which I love.

I reduced the icon size to 45x45 and the popup delay to 250.  Have had one abend, but quickly restarted without a problem.   I don't like to clutter my system with unnecessary/infrequently used  software, but 3d Launch Pad gets to stay.

Marketplace / Relish v.2.2 (Closed)
« on: January 10, 2019, 10:41:58 pm »
Update:  I was able to obtain a copy of v.2.2

<<I would like to purchase a copy of Sundial's Relish v.2.2 ($300) if anyone has a license they are no longer using.  I am looking for a valid licensed copy, but I don't need the original media or documentation.>>

Thank you!

From what you describe, CPU temp isn't the problem.  As a note, the BIOS often times uses a sensor that has nothing to do with the on-die sensors.  I have had stability issues due to a single core overheating on a large multi core chip.  Using something like lm-sensors while loading all cores with mprime is good way to read the temps across each core to detect how evenly each is getting cooled.  A large difference in temps would have me reapplying compound.

Booting from a Linux live CD will give you access to a variety of utilities for testing.

I can be pretty lazy and would wait for the problem to happen again before spending the time to diagnose the problem.  It's good there was no file corruption.

DaveI am sure though, the machine is, hardware-wise, fine.

I took too long to post and didn't see your updated post.  If a software issue, hopefully it was a fluke and the last time you see it. 

If you're not using JFS, you might consider changing over to it.  JFS is extremely robust having been used on midrange AIX systems for many years and is great at recovering from unclean reboots/remounts.

All the posts provide good information.  A hardware fault would be my first guess.

I suspect many are running OS/2 on older machines.  It could be something as simple as needing to reapply thermal compound on the CPU, which has a limited life of about 4 years (or less).  I proactively change my power supplies at about 5 years.  You might consider reading the SMART data from your storage device to identify any errors, run memtest overnight to test your RAM, and run MPrime's torture test (Option #15) to see if you can generate any errors.  Turn off all unused mobo features in your BIOS. I normally would recommend to make sure you're current on available device drivers, but this is OS/2 :-) 

Hardware / Re: Is there any SCSI PCI Express card supported by OS/2 ?

Thanks, that's great to hear ! Since you are using VMWare, did you succeed in getting multiple CPUs (SMP) to work under ArcaOS as a guest ?

Yes and no.  I have been using four logical cores (Xeon E5-2699 v4) without any issues, but oddly when I exceed four cores, I begin to have problems with certain applications (e.g., ZOC abends).  I believe the issues I have seen are isolated to certain applications due to their design.  Under VMware, I have used as many as 10 logical cores using the ArcaOS kernel, and the OS has been very stable.

<<Is there any SCSI card that is PCI Express that has a native driver for OS/2 ? Ideally, I would like to find such a card if one exists.>>


Delayed in responding as I just completed my registration...   

I am using VMware Workstation on Linux to run ArcaOS.  With this setup, you can use virtually any PCIe SCSI card.   I define my linux SCSI device (/dev/sgx) to VMware, then select any SCSI card supported by OS/2 to install drivers, making the SCSI device available to OS/2.  I'm using an LSI PCIe SCSI card on Linux, but I have installed drivers for an old BusLogic ISA bus SCSI card on OS/2 to gain access to the Linux mounted SCSI device.

While I do backup my OS/2 VM to LTO, I also like to perform an OS/2 backup to DAT so I can selectively restore individuals files.
