[LU-14056] MDT filesystem full, fsck crashing

• Type: Bug
• Resolution: Fixed
• Priority: Major
• Affects Version/s: Lustre 2.12.2
• Environment: EL 7.6.1810 x86_64
• Severity: 3

Description

MDT filesystem filled up, MDS crashed and would crash again shortly after mounting filesystem . Disabled mount on boot and mounted the MDT as ldiskfs to make some space. After deleting some files, unmounted and ran a fsck.ext4. This has crashed twice after running for 6-7 days, the first time the MDS was unresponsive and had to be rebooted, the second time I could capture a backtrace. I remounted the MDT - still showing 100% (could well be because the fsck didn't finish). Not sure what to do next.
