[zfs-discuss] Re: zfs hot spare not automatically getting used

[Jim Hranicky]

I know this isn't necessarily ZFS specific, but after I reboot I spin the 
drives back
up, but nothing I do (devfsadm, disks, etc) can get them seen again until the
next reboot.

I've got some older scsi drives in an old Andataco Gigaraid enclosure which
I thought supported hot-swap, but I seem unable to hot swap them in. The PC
has an adaptec 39160 card in it and I'm running Nevada b51. Is this not a 
setup that can support hot swap? Or is there something I have to do other
than devfsadm to get the scsi bus rescanned?

OK, spun down the drives again. Here's that output:

I just realized that I changed the configuration, so that doesn't reflect 
a system with spares, sorry. 

However, I reinitialized the pool and spun down one of the drives and 
everything is working as it should:


pool: zmir
state: DEGRADED
   status: One or more devices could not be opened.  Sufficient replicas exist 
for
   the pool to continue functioning in a degraded state.
   action: Attach the missing device and online it using 'zpool online'.

I'm just not sure if it will always work. 


I'll try a few different configs and see what happens.

[zfs-discuss] Re: zfs hot spare not automatically getting used

[Jim Hranicky]

So is there a command to make the spare get used, or
so I have to remove it as a spare and add it if it doesn't
get automatically used?

Is this a bug to be fixed, or will this always be the case when
the disks aren't exactly the same size?
