The docs recommend an MDS volume around 1-2% of the size of your total data volume.
There¹s a lot of useful information in the manual about sizing, etc., so you¹re probably better off reading them to see what suits your environment but the 1-2% rule of thumb nonetheless applies. The key element if you¹re setting up an active/passive MDS pair is that you need to be able to see the same device from both MDS nodes; the active one will mount it, the passive one will wait until it¹s needed (i.e. the active MDS encounters a failure). It¹s essential that they not mount it simultaneously, though, or wicked corruption is likely to occur. hth, Klaus On 11/2/07 1:45 PM, "Mertol Ozyoney" <[EMAIL PROTECTED]>did etch on stone tablets: > Hi All ; > > What kind of server and storage would you suggest for a 600 TB (Net) lustre > system? > > I plan on using a 2 or 4 socket Quad Core Server with a lot of RAM (active > passive cluster) with 24 x 146 GB 15k RPM drives.
