EXT3-fs warning in dmesg

Hello,

i got a 4 TB Sharespace Drive wich has gone in read only the dmesg show this :

EXT3-fs warning (device dm-0): ext3_clear_journal_err: Filesystem error recorded from previous mount: IO failure
EXT3-fs warning (device dm-0): ext3_clear_journal_err: Marking fs in need of filesystem check.
EXT3-fs warning: mounting fs with errors, running e2fsck is recommended

any hints how i can resolve this ?

The NAS is running on 2.2.91 with MioNet 4.3.1.1

Sounds like data corruption to me… What if you restore it to factory defaults or rebuild the RAID to clean it? Remeber any of the 2 will erase the data.
