Title: HELP! weird raid change after upgrade to 5.6
Post by: Greg on January 23, 2003, 02:45:22 AM

Hello

An upgrade from 5.1.2 to 5.6 was done on a system with 2 drives using the SME software raid. We now have a raid alarm. The weird thing is the drive allocation was changed in the upgrade?

example

before upgrade  md2 : active raid1 hdc1[1] hda1[0] 264960 blocks [2/2] [UU]
after upgrade     md2 : active raid1 hda1[0] hdc1[1] 264960 blocks [2/2] [UU]

before upgrade  md0 : active raid1 hdc5[1] hda5[0] 15936 blocks [2/2] [UU]
after upgrade    md0 : active raid1 hda5[0] hdc5[1] 15936 blocks [2/2] [UU]

before upgrade md1 : active raid1 hdc6[1] hda6[0] 38796864 blocks [2/2] [UU]
after upgrade   md1 : active raid1 hda6[0] hdc6[1]  38796864 blocks [2/2] [UU]

These drives are on separate cables. What would be the best way to get them back into sync?

Copy of raid alert as follows

last known good config was...

md2 : active raid1 hdc1[1] hda1[0] 264960 blocks [2/2] [UU]
md0 : active raid1 hdc5[1] hda5[0] 15936 blocks [2/2] [UU]
md1 : active raid1 hdc6[1] hda6[0] 38796864 blocks [2/2] [UU] unused devices:

the new configuration is now...

md1 : active raid1 hda6[0] hdc6[1]  38796864 blocks [2/2] [UU]
md0 : active raid1 hda5[0] hdc5[1] 15936 blocks [2/2] [UU]
md2 : active raid1 hda1[0] hdc1[1] 264960 blocks [2/2] [UU] unused devices:

Just run raidmonitor -iv, and these should go away.
