can anyone confirm what the preferred tool is in 5.3-STABLE, vinum or gvinum ? Is gvinum ready for production use in a RAID5 config ?

As far as I can tell, it would be wise to update to 5-STABLE or wait for 5.4 in order to use gvinum with RAID-5 configurations. There have been some important fixes to gvinum wrt RAID-5 on the -STABLE branch. Do _not_ use regular vinum on 5-STABLE, it will not work. --Stijn -- An Orb is for life, not just for Christmas. -------------- next part -------------- A non-text attachment was scrubbed...

Sorry to butt in on your thread, but it seems relevant. I am having problems with gvinum under 5-STABLE and a RAID 0 array of two disks. The array works perfectly until reboot. Then, when the machine comes back up the plexes are marked as stale. Issuing these commands fixes the problem until the next reboot: gvinum setstate up storage.p0.s0 gvinum setstate up storage.p0.s1 Things I've tried: * Googling for answers * commenting out the fstab entry at boot and then manually mounting the partition after boot * inserting gvinum in /boot/loader.conf * copying the vinum script in /etc/rc.d/vinum and making a gvinum equivalent * trying to shutdown gvinum at shutdown time (but "gvinum stop" doesn't work) * fsck * rebuilding gvinum array Is there some shutdown procedure that should gracefully shutdown the RAID? There is a process which opens files on the RAID and runs continuously until shutdown. Could it be holding the RAID open too long and could this staleness? From what I can tell the staleness doesn't affect any data - everything is OK once brought up.
