OK, so I have a RAID1 array used as Journal disk for two 14TB OSTs. this has 2 x
2GB partitions on 2 x 2TB physical disks.
[root@silicon ~]# fdisk -l /dev/sdav
Disk /dev/sdav: 2000.3 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdav1 1 56 449788+ fd Linux raid autodetect
/dev/sdav2 57 112 449820 fd Linux raid autodetect
One of the RAID1 disks is about to fail and before I replace it I would like to
back up the journals so I can recover.
There doesn’t seem to be any information on how to do this.
Can I mount -t ldiskfs and then rsync the information somewhere just in case the
RAID1 replacement doesn’t work?
What is the procedure for this?
Let me know.
Thanks!
