There's also the overhead of the JFS filesystem. When you create with "Large File" also don't use defaults, use "Number of Bytes per inode" of at least 32768 and this will give you a few more hundred MB of space. After FS is created, use df -k to see what you actually have available and use that.
(Remember the MB vs million bytes!!) David Longo >>> [EMAIL PROTECTED] 11/21/01 10:51AM >>> In the Admin Reference for v3.7 it says... the allocated file size is always a multiple of 4MB plus an additional 1MB ofr overhead). Don't know how much that will help answer your question. Thanks, Jon -----Original Message----- From: Loon, E.J. van - SPLXM [mailto:[EMAIL PROTECTED]] Sent: Wednesday, November 21, 2001 9:54 AM To: [EMAIL PROTECTED] Subject: dsmfmt question Hi *SM-ers! I will replace my 9 Gb. SSA disks in the very near future. The new disks (36 Gb. 10.000 rpm) will have to be added to the diskpool one by one. I remember from the last time that it was quite difficult to allocate a disk file which fills the disk completely. If you have, for instance, a 9 Gb. disk, you cannot create a 9 Gb. file by issuing a DSMFMT -G -DATA filename 9. This results in an error indicating the there isn't enough space available. Apparently the dsmfmt utility needs a little bit overhead space. Does anybody know how to calculate the maximum space one can specify to fill the disk to it's maximum? Thanks in advance for any reply!!!
