<div><font size="2" face="Default Monospace,Courier New,Courier,monospace" >Good morning,<br><br>Was wondering if anyone could point me to any tips or provide some regarding choosing vdisk size? My understanding is that too small is a waste of resources in the form of overhead, and that there is an upper limit. but that generally within a pool, you want them to be the same size, so that if you aren’t allocating the entire storage space on the system straight off, you’ll need to choose a reasonable size or be left with unusable space (eg. you will waste space if you went with, say, 200 GB vdisk sizes on a 500 GB array).<br><br>Anyone have any tips? Do people just generally allocate the whole thing and have one 2 vdisks (redundancy)? Seems you have some more flexibility if you don’t do that and have to, say, create a storage pool or filesystem from scratch to take advantage of features in a newer FS version or what have you.<br><br>Thanks for the help — spent a lot of time looking for this previously, but never asked on the list.<br> <br>--<br>____<br>|| \\UTGERS, |---------------------------*O*---------------------------<br>||_// the State | Ryan Novosielski - novosirj@rutgers.edu<br>|| \\ University | Sr. Technologist - 973/972.0922 (2x0922) ~*~ RBHS Campus<br>|| \\ of NJ | Office of Advanced Research Computing - MSB C630, Newark<br> `'<br><br>_______________________________________________<br>gpfsug-discuss mailing list<br>gpfsug-discuss at spectrumscale.org<br><a href="http://gpfsug.org/mailman/listinfo/gpfsug-discuss" target="_blank">http://gpfsug.org/mailman/listinfo/gpfsug-discuss</a> </font><br> </div></blockquote>
