Hi all, We are running CentOS 5.2 64bit as our file server. Currently, we used GFS (with CLVM underneath it) as our filesystem (for our multiple 2TB SAN volume exports) since we plan to add more file servers (serving the same contents) later on. The issue we are facing at the moment is we found out that command such as 'ls' gives a very slow response.(e.g 3-4minutes for the outputs of ls

The documentation for 5.2 indicates the glock_purge tunable parameter is present for GFS in its example output from `gfs_tool gettune`. However, I just upgraded a 5.1 system to 5.2 and everything looks good except for the mysterious absence of the glock_purge parameter. Any ideas as to why this tunable which I was looking forward to getting is missing? - James Thompson
