Hi, everyone.
I have several servers with large UFS partitions (>100TB).
Physically it is RAID-6 on MegaRaid 9361.
If i try to run fsck on them, i get same error on all servers:
Code:
** Phase 5 - Check Cyl groups
fsck_ffs: inoinfo: inumber 18446744071562087424 out of range
inumber is exact same on all servers.
tested on clean and drity filesystems with same result.
And without succsessful run of fsck i can't remove dirty flag from filesystem
This is a fresh install of FreeBSD 12.1 and filesystem created in 12.1 from scratch with default options.
This is file storage for videoproduction. So, there is not too much files and they is relatively big.
Code:
# find . -type f -print | wc -l
251485
# find . -type d -print | wc -l
48351
Maybe i doing something wrong?
