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.
[EMAIL PROTECTED] 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 raidhotadd and all was well again. I waited until the disks had completely resynced and tried again. Same result.
Below are raidtab and fstab, neither of which have been altered by me.
[EMAIL PROTECTED] etc]# cat raidtab raiddev /dev/md0 raid-level 5 nr-raid-disks 3 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device /dev/hde1 raid-disk 0 device /dev/hdf1 raid-disk 1 device /dev/hdg1 raid-disk 2
also, fstab is quite straightforward.
[EMAIL PROTECTED] etc]# cat fstab
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
/dev/md0 /home ext3 defaults 1 2
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
Any suggestions as to why?
