Cheers Felix I'm about to try; I have my home server stuck at 4.11 because I could never get gvinum to work reliably with 5.x, and the drives I had wouldn't work with two different hardware RAID controllers (ex EMC ST446xxx's, a DPT/Adaptec controller and a LSI controller - apparently only certain EMC BIOS versions will work, and I don't have them). I did find a posting by someone who installed gvinum/RAID5 recently (under 6.X) but there was nothing about stability. Mike Squires UNIX(tm) at home since 1986 I'm running gvinum on a PowerEdge 2450 with an external Adaptec SCSI card connected to a PowerVault 712 (I think, at least an old one), also running RAID 5. This runs on FreeBSD 6.1. It was not that hard to set it up, as the handbook has well written documentation about it. However, there is one thing you should know: Never, ever, edit the gvinum config file directly when you want to remove drives from your array. Use the gvinum shell for that. Immediately removing them from the config file will cause kernel panics. In fact, only use the config file to define your array: Make changes via the shell. Maybe it sounds logic to you, but I had about 10 kernel panics before I figured that out. Overall if you follow exactly what's being said in the documentation it is quite okay, but my gvinum installation is still missing features. The Google Summer of Code project has invested quite a lot of time in fixing the missing features in gvinum, so overall I think it should be a fairly complete suite now. I'm not sure if those changes are already commited to the source tree, but I guess they are. My gvinum installation certainly is stable, however. And the server is fairly important, so I can't risk upgrading gvinum and maybe ruin the array.

In my experience gvinum is stable until a drive fails. Good luck and let us know what happens! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: State of gvinum RAID-5
Hi, I tried gvinum RAID-5 with a 5-Stable around the time when 5.1 or 5.2 was released (afair) and back then it basically sucked big time. Raid worked as long as nothing failed, but reconstructing a drive was somewhere between very painful and not possible. I agree. Now I will have to upgrade hardware soon, which means I could switch from NetBSD (and Raidframe) to FreeBSD (with gvinum) again. I would like to because NetBSD seems to have some kind of memory leak in connection with Samba and large or many files, but I'd rather have a somewhat unstable Samba than an unstable Raid, so what's the state of affairs? I have been running gvinum RAID-5 on a ProLiant machine for 6 months now and I hadn't had any problems so far. First I installed FreeBSD 5.4 at that time but the RAID array crashed when there was an unclean reboot. After that I installed FreeBSD 6.1 and for now (knock knock knock) everything looks to work fine. However, I hadn't had a disk crash yet so I can't tell what exactly happens when one of the disks dies. I also run Samba and NOD32fac viruschecking on the same server and it works just great.
