I don't think quotas actually constrain the allocation ranges on disk. If the array supports TRIM you could use manual trim, as in http://lwn.net/Articles/345020/ Essentially hdparm allocates large files and then executes TRIM on them manually, which allows the array to reclaim space. Some of the other file systems (like XFS, ext4, btrfs) are also gaining automatic TRIM support, but I haven't heard of anyone working on that for JFS. -Andi -- [email protected] -- Speaking for myself only. ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ Jfs-discussion mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jfs-discussion
