Group size must divide evenly into draid size
|
|
|
|
|
E.g., 30 drives can only support
|
|
|
|
|
3 drive group
|
|
|
|
|
5 drive group
|
|
|
|
|
10 drive group
|
|
|
|
|
15 drive group
|
|
|
|
|
|
|
|
|
|
Only need to specify group size at creation
|
|
|
|
|
|
|
|
|
|
Group Size - the number of pieces the data is partitioned into plus the amount of parity
|
|
|
|
|
o The amount of parity determines the redundancy
|
|
|
|
|
o The number of data pieces determines the overhead
|
|
|
|
|
|
|
|
|
|
dRAID Size - the number of drives used for data
|
|
|
|
|
(Does not include spare drives)

Below is a severely degraded pool with all physical spares in use; despite the raidz1 level it has
|
|
|
|
|
sustained (6) simultaneous drive failures; one more with no replacements will kill the pool
|
|
|
|
|
and there are no vspares allocated, but it was configured for maximum available space:
|
|
|
|
|
|
2021-07-05 10:34:40 -05:00
|
|
|
pool: zdraidtest
|
|
|
|
|
state: DEGRADED
|
|
|
|
|
status: One or more devices could not be used because the label is missing or

|
|
|
invalid. Sufficient replicas exist for the pool to continue
|
|
|
|
|
functioning in a degraded state.
|
|
|
|
|
action: Replace the device using 'zpool replace'.

NOTE if you simulate/take a drive offline, you cant just "echo online" to it later, that wont bring it back up!
|
|
|
|
|
try rescan-scsi-bus.sh or reboot
|
|
|
|
|
|
|
|
|
|
FIX: if a drive is offline, replace it temporarily with a builtin spare:

HOWTO fix the above situation with the same disk (you rebooted / it came back online) and decouple the in-use spare:
|
|
|
|
|
|
|
|
|
|
zpool export -a
|
|
|
|
|
|
|
|
|
|
fdisk -l /dev/sdd # scsi-SATA_VBOX_HARDDISK_VBbcc6c97e-f68b8368
|
|
|
|
|
zpool labelclear /dev/sdd
|
|
|
|
|
zpool labelclear -f /dev/sdd1
|
|
|
|
|
|
|
|
|
|
zpool import -a
|
|
|
|
|
zpool status -v # This will show a degraded pool with a missing disk
|
|
|
|
|
|
|
|
|
|
# This wont work but gives useful info:
|
|
|
|
|
zpool replace zdraidtest spare-2 scsi-SATA_VBOX_HARDDISK_VBbcc6c97e-f68b8368 # got error, use detach
|
|
|
|
|
|
|
|
|
|
zpool detach zdraidtest 2582498653363374334 # this was listed as UNAVAIL with the spare in-use underneath it
|
|
|
|
|
zpool status -v # should now show only the spare where sdd was
|
|
|
|
|
|
|
|
|
|
# we labelcleared it so it should be ready for re-use;
|
|
|
|
|
# if you want to be really thorough you can DD zeros to the entire drive but not really necessary
|
|
|
|
|
zpool replace zdraidtest draid2-0-0 scsi-SATA_VBOX_HARDDISK_VBbcc6c97e-f68b8368 # same disk (sdd) but labelcleared
|
|
|
|
|
zpool status -v
|
