Altering inode values in VMFS3

[resh]

Hi There..

Is there any way to alter the inode value of a VMFS volume either while creation of the volume or at a later point of time ?

Requirement :

Increase the number of files (not the size) in a VMFS volume.

Would appreciate if any info is send on the same..

Regds,

Resh.

Hello,

There is no way to change the number of inodes. VMFS is a closed filesystem. The idea is to increase the number of LUNs in used instead of increasing the number of files per LUN. The reason for this is that with more LUNs you can run more simultaneous actions across the LUNs to mitigate the number of SCSI Reservation Conflicts.

The limit on a VMFS-3 is something like 30,000 files. VMware writes in the 'Configuration Maximums for VMware Infrastructure 3' document that this is enough for the max. number of virtual machines. VMFS is not a general filestore

The default limit for VMFS-2 is 256, but it can be changed with, e.g. "vmkfstools -C -n 1024" during creation.
