linux fc5 with 3 raid5 arrays + one LVM over those arrays

Marc Verbeke <Marc.Verbeke@pandora.be> · Mon, 25 Sep 2006 07:05:27 +0200

I hope I can get through this time.

7 USB drives
Partitions of 94 GB
RAID5
md1 md2 + spare
md3 without spare
lvmsystem over md1 md2 dm3 totalling about 1.2 Terabytes

keep on eye on

/dev/sdg1             lvm2 --    87.55G  is recovering for md1 and is 8e
/dev/sdg3             free       15.55G  not used in any combination
