You guys hit it right on...."vxfs is dynamic" and so basically the "inodes are
created on the fly" and this would be the reason why "'df' does not work" (only
does so with ufs). So one answer to the question of how many inodes for vxfs, is
'as many as it needs'. As Darren mentioned, "there is eventually a limit" and I
would think that would be related to disk space.
Some of the responses were:
(Jim Vandevegt)
"It's easiest to say that inodes are dynamic in VxFS. It really doesn't use
them. It creates them to be compatible with UFS. VxFS uses extent-based
allocation rather than the block-based UFS controlled by inodes."
(Darren Dunham)
"VxFS does not have a fixed number of indodes as UFS does. They can be
created on the fly as needed. So df doesn't display them. There is eventaully a
limit, but it is very large."
(Robert Brockway)
"Are you sure they even have inodes? Not all filesystems reference data this
way (although all tradional unix filesystems certainly do). I'm honestly not
sure about vxfs."
(Simon Bernard Drolet)
"Under vxfs, the number of inode is dynamic... I don't have a vxfs in
front of me, have you tried df -e ?"
chimo,
-deb
ORIGINAL QUESTION:
Is there a way of finding out how many inodes there are in a system?
OS is Solaris 8/Veritas Volume Manager used
Note: df -F ufs -o i works well for ufs file systems but not for filesystems
created with Veritas (vxfs) I definitely am missing something....
