This cluster is out of support. I’ve run the commands listed in KB 8514


Detailed information for fs_inconsistency_check:
FAIL: Filesystem errors found on CVM on the below device(s):
Device: md2, Partition: home, Max Mount Count: -1

Refer to KB 8514 ( for details on fs_inconsistency_check or Recheck with: ncc health_checks system_checks fs_inconsistency_check --cvm_list=
| State         | Count |
| Fail          | 1     |

egrep -H "^" `ls /sys/fs/ext4/*/errors_count` | grep md2


for i in `sudo blkid | awk -F : '!/xfs|iso9660/{print $1}'`;do echo $i;sudo tune2fs -l $i | egrep 'Filesystem state|Last checked|Maximum|error|orphan';done

Filesystem state:         clean with errors

I’ve tried stopping and restarting the cluster. I thought Linux would clean the filesystem on reboot, but it did not. I saw one person resond that the fix is to rebuild the CVM. Any help would be appreciated.

I had a customer having the same problem as you described… Customer wanted to reboot the cvm for the same reason. I told them, that won’t be a solution.

I guided them to support, but I see you don’t have that option.

When I got some feedback,I will leave a note here… Hopefully I am able to guide you to a solution. However, no guarantee, as this forum is not a replacement for support.
