I don't think it's "like ext4," however, which reserves blocks for the root user. I don't believe the reserved blocks in XFS are accessible for file allocation by any user unless the reserve pool is modified as such. > Can you provide the specific command. > The following command can get/set the reserved block count on an active mount: xfs_io -x -c "resblks" <mnt> Note that this can lead to problems if reduced too much and all space is consumed, as sometimes block allocation is required to perform space freeing operations (removing a file, etc.). This is probably a reason the resblks command is only available in xfs_io expert mode. ;) Brian > Thanks > Mukul > _______________________________________________ > xfs mailing list > xfs@xxxxxxxxxxx > http://oss.sgi.com/mailman/listinfo/xfs _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
