[LU-12912] fsck looping

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Environment: DDN sfa12k IB attached to Dell R730 servers. TOSS 3.5.1 (rhel 7.5)/Lustre 2.10.5/e2fsprogs-1.42.13.wc6-7.el7.x86_64

Description

An OST on one of our systems went read-only last week. Today I unmounted the particular OST and ran a read-only fsck against the target. During the fsck the check got stuck on one inode and kept repeating the message:

Block <foo> (<bar>) causes symlink to be too big. IGNORE.

(repeats 12 times)

Too many illegal blocks in inode 33023185.

Clear inode? no

Suppress message? no

 

This continually repeats. Since it was a read-only fsck we terminated it and remounted the file system without going any further with the file system repair without consulting with you first. 

This is on a classified system so providing explicit detail will be difficult. Note: This problem is similar to LU-12386 that was posted last year.
