I use RAID-5 with 5 disks, using the RAID array for the entire filesystem -
booting from a floppy. Kernel 2.2.13ac2, raidtools 0.90.
Persistent-superblock is set to 1 and there is no spare-disk. I just got an
extra disk and want to add it as a spare-disk. How can I update the
configuration without destroying any data?
NB, I don't want to expand or change the array in any way, just make the
system know that there is an extra disk ready to kick in if one of the
current disks crashes. The new disk is formated like the others, and I
updated raidtab to include the new spare-disk.
The man-page for mkraid says:
"Note that initializing RAID devices destroys all of the data on the
consituent devices."
This is a production system and I'm really afraid to mess up. What shall I
do?
Best regards, and a Merry Christmas
