Is there a limit to the number of files on a vxfs filesystem

Is there a limit to the number of files on a vxfs filesystem.

Thanks!

One of the first limits you might hit is the number of available inodes:

bdf -i

[Joseph C. Denman]

I don't think there is really a limit except for the number of inodes available on the filesystem. You can view the number if inodes with the df command.

df -i /data1

However, number of inodes will very from filesystem to filesystem depending on size, block size,.......

No.

In a vxfs filesystem inode allocation will be dynamically increased if you run out of inodes. Thus, the limitation is actually on total space. If the filesystem runs out of space, therte will be no room to allocate new inodes (or to write a new file, for that matter).

Hi Nancy:

There are no limits to the number of inodes in a VxFS filesystem.

The maximum number of directories in a VxFS filesystem has been limited to 32,767. This can be increased to a maximum of 2,147,483,647 [the maxiumum integer size] by tuning the 'vx_maxlink' kernel parameter. Patch PHKL_24201 implements this parameter.

Alan and James,
Thanks for the info. It answered my ? completely. For some reason I am not able to assign points for the reponses I will try to assign in the morning.
Thanks again.

Hi,
I have facing the same problem like you, now HP has provides the patch to extend the maximum number from 32,767 to 65,535. You have to install the following patch:

PHKL_24201

Anyway don't add the number more than 65,535 to the kernel parameters
