Storage Pool / Hot Spare - Any Constraints?

there questions hot spares in mind:

- there constraint on hot spares (i.e. disk size should equal or exceed biggest disk in pool)?
- if not: storage spaces active 2 or more hot spares whenever required? (assuming there 10 1gb hotspares present , 3 tb disk fails - activate 3 hotspares, or if there not enough room on active disks?)
- if activate multiple hotspares when required: storage spaces prefer rebuild on existing disks, or activate 1 many hotspares @ time?

then there question hotspare activation , rebuilding in general. various posts derrived automatic rebuild not going happen, when no hot spare present. save run "get-virtualdisk | repair-virtualdisk -asjob" in cronjob fashion on daily basis? (i noted, repair-command finishes within no time, if there nothing repair)

what if rebuild taking place , command executed again? ignored? queued? concurrent exectuion?

edit: oh, (or many) hot spare activated, when pool runs out of storage on thin-provisioned virtual disks?

hi,

cannot test such environment, here understanding of these questions. if there unclear please let me know , i'll glad discuss you.

1. no disk size limitation. recommended use disk larger or equal size.

2. 1 disk selected when 1 disk corrupted in storage pool. not take 2 (or more) disks replace 1 corrpted disk.

3. personal understanding: when new disk added replacing, not auto-repair - new data start written new disk working pool/virtual disk old data still there - warning still there until retired corrupted disk , run repair. that's why repair finished disk corrupted , new disk added.

4. cannot confirm if auto-running repair good. re-run repair should not reset repair process, without retire corrupted disk first, repair still not work on old data on pool/virtual disk.
