Hi, Scenario is the following:
- Lustre 1.8.1.1 - 3 Lustre filesystems, fully redundant (two networks, OSSs on active/active, MDSs on active/passive) - 1 MGS, 1 MDT, 2 OSTs - For the MGT, 128MB were allocated, following Lustre's manual recommendations - The MGT is already out of space, and a "ls" of the MGT is showing files are 8MB, like: -rw-r--r-- 1 root root 8.0M Dec 2 15:11 devfs-client -rw-r--r-- 1 root root 8.0M Dec 2 15:11 devfs-MDT0000 -rw-r--r-- 1 root root 8.0M Dec 2 16:42 devfs-OST0000 Other lustre filesystems I have worked on show much smaller files. A "dumpe2fs" on this MGT does not show anything strange like huge block sizes, etc. Question is, why are these files so big and how can we "shrink" them? Is it possible to run --writeconf to fix this? Thanks, Jeffrey A.
