atacontrol Raid, cannot re-add member to array
Click here to view our e-mail legal notice: http://www.swistgroup.com/email.htm or call: +27 21 888 7920 Hi all, I'm investigating atacontrol raid as an alternative to vinum. So far it has worked great. That's until I unplugged one of the array members. The system boots up fine from the second disk, but the problem ... I can't get atacontrol to rebuild the mirror onto the disk that was removed. I have tried every command on the atacontrol man page, but to no avail. OS : FreeBSD 4.10 System : P3 IDE controller : Intel ICH2 ATA100 controller and 2 x 40 GB disks. On FreeBSD 5 atacontrol has an additional command "addspare" that I have used with success to add a disk to a RAID1 array and rebuild it. Now that you know some of the details, here are the questions 1.. How "safe" is the atacontrol raid feature? 2.. How do I rebuild an atacontrol RAID1 array on FreeBSD 4.10? Any help would be appreciated, I have been at it the whole day!

HPT372 e.g. is completley unsupported in -stable. I've never tried ataraid with "non-raid" controllers but I doubt that detach/attach would work. I asked Søren about the missing addspare in -stable but never got any answer. I just had extreme problems with ataraid on -current and am awaiting some response about these issues, I just can hope that some time ataraid will be lifted to what the man page promises. -Harry > pgpt2aMP0gYGO.pgp Description: signature

It does work, you "just" have to hotswap the disk [1]. I tried it some time ago, and I successfully did a rebuild, though I did kill one of the disks shortly after since I tried to plug in the power cable the wrong way during another test (yes that's stupid, I know :-) ). > I asked Søren about the missing addspare in -stable > but never got any answer. AFAIK Søren does not update the ata driver in stable since it's somewhat different than the one in -CURRENT, and he does not have the time to maintain both codebases. AFAIR somebody made a patch for addspare functionality on -STABLE not to long ago. It should be in GNATS somewhere. > I just had extreme problems with ataraid on -current and am awaiting some > response about these issues, I just can hope that some time ataraid will be > lifted to what the man page promises. Well, I'm using it just fine on my main mailserver (running 5.2.1) but that's a RAID1 with standard a ATA controller.

Ughh, if I knew that 3 days eralier First, thank you very much for wour work, but since I couldn't get a promise Fasttrak100 tx2 over the weekend (which is very well supported by Sørens ataraid) I replaced my sil0680 with a hpt372 and played with the original HighPoint drivers (http://www.highpoint-tech.com/USA/b372.htm#FreeBSD) and although the module I'm using is for 4.9, it works flawlessly on 4.10-stable. Via sysctl hpt37x2.status you can use all functions like with the bios, also auto rebuild et cetera works perfectly. (alias raidinfo 'sysctl hpt37x2.status') The main reason why I couldn't use the hpt37(2) with 4.10 was that if one drive fails, ataraid removes the drive from the raid configuration. If now the same drives returnes (like it happens sometimes after a reboot) you have two (ar0 and ar1) arrays. Now you have to know which drive failed and which one the controller reports as remaining drive for the original array and dd (if=/dev/zero of=/dev/ad? count=63) the opposite drive. Otherwise the system ends up in booting from ar0, which in my case was the "failed" disk, returning after a reboot, and so I had a inconsistent several weeks old system. Your patch my be great for all sil0680 useres but hpt370 users really should use the manufacturers driver. You can see a dmesg with them at http://www.schmalzbauer.de/netz/dmesg.korso Best regards, -Harry > > Doug A. pgpMWaRFAIT5b.pgp Description: signature

Like said at the list, thank you. But for a few hours the experimenting machine from the last three days turned productive (as you can see in the header). I'm really sorry, but I'm not brave enough to try your patch with this system. It's really quiet horrible if my internal mta and much more painful my IMAP server, which is on that machine, dies. But if I'll have a chance to test it I'll do it immediately and drop you a note. (I have only a spare sil0680 and hopefully a FastTrak100 TX2 but this one is perfectly sopported anyway) Thank you, -Harry > > Doug A. > ___ > [EMAIL PROTECTED] mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "[EMAIL PROTECTED]" pgpro4Yp61oPt.pgp Description: signature

So does this mean ATA RAID doesn't work on "non-raid" controllers that have non-hot swappable drives attached? (E.g., a drive get hard errors, is marked as failed and the RAID as DEGRADED, and you have to shut down the machine to remove and replace it---but ATA RAID won't recognise it/rebuild onto it when you reboot with the replacement drive.) If that is the case, the man page really should note that serious limitation. I have tried the detach/attach on a non-raid controller to simulate failure and have *never* managed to get rebuild to work. I've also tried the shutdown/remove/replace/reboot method but, again, *never* managed to get rebuild to work on a "non-raid" controller. :-( I've never had any hotswap-capable drives to test the hot-swap replacement/rebuild method. :-( > Well, I'm using it just fine on my main mailserver (running 5.2.1) but > that's a RAID1 with standard a ATA controller. I wish it would work for me. :-) I have a non-raid controller 5.2.1 system that I tried it on (with non-hot swap drives) that I eventually had to bail and use Vinum on. Alas, Vinum seems to be rotting at a fast pace in CURRENT, so I'm worried about the prospect of being able to upgrade that system when 5.3 rolls around... :-( Cheers, Paul. -- e-mail: [EMAIL PROTECTED] "Without music to decorate it, time is just a bunch of boring production deadlines or dates by which bills must be paid." --- Frank Vincent Zappa ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
