Hi all - I've run into a problem several times lately where despite my SNMP checker warning me about machines with < 5% free disk space, I still ran out of disk space. I had never had time to track it down until it happened again this morning. I was really confounded by the fact that df -h shows the following:
Filesystem Size Used Avail Use% Mounted on /dev/sda1 99G 93G 868M 100% / Turns out that ext2/3 reserves 5% of the filesystem space for the root user to allow for recovery from a disk full condition, so you actually run out of space at 95% usage. It turns out that this is really only necessary on root partitions, and 5% on large disks is probably really overkill (and since mine are VMs, anyway, I can mount the filesystem and fix the problem or simply grow the device & filesystem without logging in easily enough). Here's a more in depth article on it - hope this helps somebody else avoid this frustration! http://boncey.org/2006_11_18_reclaiming_ext3_disk_space Jeremy Nelson _______________________________________________ Fwlug mailing list [email protected] http://fortwaynelug.org/mailman/listinfo/fwlug_fortwaynelug.org
