Hi, I'm trying to find out how to replace a drive in a vinum RAID-5 volume that's still working. I have the following volume (copied by hand, sorry):
V local State: up Plexes: 1 Size: 167 GB
P local.p0 R5 State: up Subdisks: 4 Size: 167 GB
S local.p0.s0 State: up PO: 0 B Size: 55 GB
S local.p0.s1 State: up PO: 512 kB Size: 55 GB
S local.p0.s2 State: up PO: 1024 kB Size: 55 GB
S local.p0.s3 State: up PO: 1536 kB Size: 55 GB
with s0..s3 on drives locala..d. Drive localc is on device /dev/ad14s1e,
and that's the IDE disk I want to replace.
So far, I've thought of doing the following:
- boot the system single user
- enter vinum
- issue 'start' to read the configuration and start all volumes
- issue 'stop localc'
- this sets the state of local.p0.s2 to degraded automatically
- stop vinum
- halt the system
- physically replace the drive
- boot the system single user
- fdisk / disklabel the new drive to include a 55GB sized vinum partition
- enter vinum
- issue 'start' to read the configuration and start all volumes
- issue 'start local.p0.s2' to revive the subdisk
Can anyone confirm that this procedure will work? Or do I have to add
a new drive to the system on the same device as the previous one?
