Hello everybody,
Every Monday night, my FreeNAS runs a scrub of my whole pool (11 drives á 10 TB configured in a RAID Z3). Today I woke up and got this messages from my FreeNAS Server:
After I got from work i shut down my server, checked all my cables and put them off and back into the hdds. It appeared that one cable came off a little because when I booted my server the whole pool was ONLINE again but I got a new message:
This brings me to my first question - why did a resilver-process took place? IIRC a resilver only takes place when a hdd is replaced and the data has to be written to the new disk.
Also, after running 'zpool status‘ i got this message:
One disk had 10 CKSUM errors - after another reboot (because of an IP change done by my router) the zpool status output does not show them anymore.
This brings me to my next question - are all my files save or is there the possibility that some files have silently corrupted ?
Also, do you think i need to replace the failing disk or did those checksum errors only appear because of the disconnection of my hdd ?

Code:
- smartd is not running - Pool Server state is DEGRADED: One or more devices has been removed by the administrator. Sufficient replicas exist for the pool to continue functioning in a degraded state..

Code:
Pool Server state is ONLINE: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state.
This brings me to my first question - why did a resilver-process took place? IIRC a resilver only takes place when a hdd is replaced and the data has to be written to the new disk.
Also, after running 'zpool status‘ i got this message:
Code:
status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear’ or replace the device with 'zpool replace‘. see: http://illumos.org/msg/ZFS-8000-9P scan: resilvered 360M in 0 day 00:01:25 with 0 errors on Mon Feb 15 17:17:40 2021
