Because the man page says that reserved blocks are used to protect root-level daemons from misbehaving would unprivileged programs try to fill the disk. And uh, to avoid fragmentation, I missed that part. OTOH I monitor disk space and never let go past 95% block usage without specific action (freeing inodes or enlarging filesystem). Would I use -m5 and oversize my filesystems (because I sell the capacity, say I sell 100GB then I need a 105GB blockdev), I would still monitor the disk usage and take action before it's 100% filled up. But I'd end up reserving more blocks without more guarantees that the -m0 case. So technically it looks wrong, but politically I'm not sure it's stupid. Or is it ? _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
