[lustre-discuss] Filesystem could not mount after e2fsck

[Stephane Thiell]

Hi Robin,

Sorry to hear about your problem.

A few questions…

Why did you run e2fsck?
Did e2fsck fix something?
What version of e2fsprogs are you using?

errno 28 is ENOSPC, what does dumpe2fs say about available space?

You can check the values of "Free blocks” and "Free inodes” using this command:

dumpe2fs -h /dev/mapper/****-MDT0000


Best,
Stephane
