[Caiman-team] [OpenIndiana Distribution - Bug #2997] Raid 1 boot disk problems when booting OI_151.1.5

[illumos project]

Issue #2997 has been updated by r a.


Last weekend I left my computer on for an extended period of time allowing the RAID1 disks to synchronise and for the filesystem to be scrubbed the computer worked fine and shutdown normally. When I started the computer on Tuesday, I left the computer for a couple of hours to see if the system was just slow. After four hours the computer had not completed its startup, so I powered of the computer. The next time I powered it on, the unit booted normally.

Bug #2997: Raid 1 boot disk problems when booting OI_151.1.5

Since upgrading to OI_151.1.5 I have experienced problems with the Raid 1 boot disk on my LSI 2411-4i constantly going into a degraded state. Initially I thought it was a disk problem and replaced the "faulty drive" but the problem remains. If I boot into the LSI controller bios and resynchronise the drives and performance a consistency check and then boot OI_151.1.5 it hangs. I have to power cycle my computer, which will then boot into OI_151.1.5 but it reports the Raid disk is in a degraded state.

If I boot into OI_151.1.4 then the problem does not occur, the disk will happily resychronise and boot normally without locking up the system.
