Whole ZFS zpool degragated after replaceing one disk in pool

#1 Post by w1t3c »

Hello,
Yesterday i had /dev/sdf disk in DEGRAGATED - too many errors state.
After replaceing hdd ...

What i done is:
zpool offline tank /dev/sdf
zpool clear tank /dev/sdf
zpool status
zpool online tank /dev/sdf
zpool replace tank /dev/sdf

after that sdf was resilvering

after some time when I check status (zpool status -v) more disks enter DEGRAGATED - too many errors state
some time after even more disks enter into DEGRAGATED - too many errors state

Now i have this :

user@backup4:/usersfs/user# zpool status -v
pool: tank
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scan: resilver in progress since Thu Jul 29 11:27:20 2021
4.14T scanned out of 42.5T at 61.1M/s, 182h40m to go
223G resilvered, 9.75% done
config:

You should read your outputs and wait for the pool to be rebuilt. Just like the outputs say....

The U.S. uses the metric system too, we have tenths, hundredths and thousandths of inches :-P
