doubt about inodes in VXFS - HPUX 11i

[Jagadesh_2]

I came to know that we can ignore the bdf -i listing as well as sar -v as far as inodes. Unlike HFS filesystems where the inode count is fixed by newfs/mkfs, VxFS filesystems build inodes as required. Therefore, bdf -i is just a sampl number and will increase automatically. It won't fill up until all disk space in the filesystem is also full.

Is there any document related to this. If so kindly let me know the link for the same.

Thanks

Hope this helps,

Hi Robert,
Thanks for the link.

I have enabled the large files option too i my vxfs filesystem. still iam getting an tivoli alert for the same. Can i ignore the alert message or is there any resolution for the same?

Hi,

http://docs.hp.com/en/B2355-90691/mkfs_vxfs.1M.html

----
Inode allocation is done dynamically. There are a minimum number of inodes allocated to the file system by mkfs, and any other inode allocations are done on an as-needed basis during file system use.

----
inosize=n

n is the on-disk inode structure size for files on the file system. The valid values are 256 and 512 bytes. The default is 256. There is usually no reason to increase the inode size, and not using the default value can adversely affect file system performance
----

inodesixe 512 + largefilesystems = 8 million inodes
