Hi,
After it came up, I had to do a manuel fsck, where it said:

This is on a very full filesystem without softupdates, and
'minfree' set to 0% (in order to live until more disks arrive).
$ tunefs -p /data
tunefs: soft updates: (-n) disabled
tunefs: maximum contiguous block count: (-a) 7
tunefs: rotational delay between contiguous blocks: (-d) 0 ms
tunefs: maximum blocks per file in a cylinder group: (-e) 4096
tunefs: minimum percentage of free space: (-m) 0%
tunefs: optimization preference: (-o) time
tunefs: should optimize for space with minfree < 8%
Any ideas ?
