Hi Chris!
It seems that a disk failed on analytics1072:
[Mon Jun 24 17:05:47 2019] EXT4-fs warning (device sdb1): ext4_end_bio:314: I/O error -5 writing to inode 13540906 (offset 0 size 53248 starting block 54383723) [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383454 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383455 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383456 [Mon Jun 24 17:05:47 2019] EXT4-fs (sdb1): previous I/O error to superblock detected [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383457 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383458 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383459 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383460 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383461 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383462 [Mon Jun 24 17:05:47 2019] Buffer I/O error on device sdb1, logical block 54383463
Megacli reports the VD with status Optimal, and I don't see any media errors registered (yet), but the kernel already flagged the partition as read only. If possible I'd ask for a new disk to swap the broken one :)
Thanks!
