The number of gfs_glock structures that currently exist in gfs.
locks held
The number of existing gfs_glock structures that are not in the UNLOCKED state.
freeze count
A freeze count greater than 0 means the file system is frozen. A freeze count of 0 means
the file system is not frozen. Each gfs_tool freeze command increments this count. Each
gfs_tool unfreeze command decrements this count.
incore inodes
The number of gfs_inode structures that currently exist in gfs.
metadata buffers
The number of gfs_bufdata structures that currently exist in gfs.
unlinked inodes
The gfs_inoded daemon links deleted inodes to a global list and cleans them up every 15
seconds (a period that is tunable). This number is the list length. It is related to the number
of gfs_unlinked structures currently in gfs.
quota IDs
The number of gfs_quota_data structures that currently exist in gfs.
incore log buffers
The number of buffers in in-memory journal log (incore log), before they are flushed to disk.
log space used
The the percentage of journal space used.
meta header cache entries
The number of gfs_meta_header_cache structures that currently exist in gfs.
glock dependencies
The number of gfs_depend structures that currently exist in gfs.
glocks on reclaim list
The number of glocks on the reclaim list.
log wraps
The number of times journal has wrapped around.
outstanding LM calls
