[gpfsug-discuss] Question about changing inode capacity safely

[Jared David Baker]

Bob, thanks for the quick reply! I had a feeling is was a fairly safe operation. Being that I joined the group post file system decision, we’ve had many discussions about different storage pools for data/metadata but mostly concluded that we would worry about it more critically on the next system at this point. Again, thanks.

I increase the inode limit on my file systems on a regular basis with no problems. I do have my data/metadata split into separate pools, but the procedure is the same.

Hello GPFS admins! I hope everybody had a great start to the new year so far.




Therefore, is there a method to safely increase the maximum inode count and could it be done during operation or should the system be unmounted? I’ve man paged / searched online and found a few hints suggesting below but was curious about its safety during operation:

      mmchfs project --inode-limit <new_max_inode_count>

Again, thank you all!
