Dear All,
I have a RAID-5 array consisting of three 40GB disks (ext3) on a machine
running Redhat 3.0ES. Recently one of the three disks failed; hdf. All
continued happily on two disks.
Yeterday I bought some new disks; 3 x 80GBs. I replaced the bad disk
with a new one, formated and partioned the new disk and did a
raidhotadd. All seemed well, see copy of lsraid -A -a md0.
[root at pinatubo root]# lsraid -A -a /dev/md0
[dev 9, 0] /dev/md0 02EF0419.559F377C.34A1ABA4.2AAE1C59 online
[dev 33, 1] /dev/hde1 02EF0419.559F377C.34A1ABA4.2AAE1C59 good
[dev 33, 65] /dev/hdf1 02EF0419.559F377C.34A1ABA4.2AAE1C59 good
[dev 34, 1] /dev/hdg1 02EF0419.559F377C.34A1ABA4.2AAE1C59 good
until I rebooted. hdf was missing. I did another raidhot add and all
was well again. I waited until the disks had completely resynced and
tried again. Same result.
Any suggestions as to why?
