All:
I am new to this list, so apologies for any ignorance, or if this
question has already been answered (though I did look through the
archives a bit). I have a raid 5 array consisting of 6 disks with no
hot spare. Here is the output of /proc/mdstat
Personalities : [raid5]
read_ahead 1024 sectors
md0 : active raid5 sdc1[0] sdh1[5] sdg1[4] sdf1[3] sde1[2] sdd1[1]
177718400 blocks level 5, 128k chunk, algorithm 2 [6/6] [UUUUUU]
unused devices: <none>
I recently obtained another identical drive, and want to add it as a hot
spare. I have seen on the list the following commands to accomplish this:
raidhotadd /dev/md0 /dev/sdi1
or
mdadm /dev/md0 -a /dev/sdi1
Where /dev/sdi1 will be the new drive. Are these the canonical ways to
do this?
I get the feeling that mdadm is more stable than raidtools, so I'm
trying to move to using just them. I do have backups, but it would sure
make me happy not to have to recover 100 GB of data from multiple DLT3xt
tapes.
Thanks in advance,
