Directory entries are also stored in the system pool and existing directories must grow in size (indirect blocks) to hold additional files/dir references as new files/dirs are created. That would be my initial guess anyways.
The “pool total” output below seems to indicate that you only have 34Mb of free space… that is definitely not good, -B From: [email protected] [mailto:[email protected]] On Behalf Of Buterbaugh, Kevin L Sent: Tuesday, January 23, 2018 11:17 AM To: gpfsug main discussion list <[email protected]> Subject: [gpfsug-discuss] Metadata only system pool Note: External Email ________________________________ Hi All, I was under the (possibly false) impression that if you have a filesystem where the system pool contains metadata only then the only thing that would cause the amount of free space in that pool to change is the creation of more inodes … is that correct? In other words, given that I have a filesystem with 130 million free (but allocated) inodes: Inode Information ----------------- Number of used inodes: 218635454 Number of free inodes: 131364674 Number of allocated inodes: 350000128 Maximum number of inodes: 350000128 I would not expect that a user creating a few hundred or thousands of files could cause a “no space left on device” error (which I’ve got one user getting). There’s plenty of free data space, BTW. Now my system pool is almost “full”: (pool total) 2.878T 34M ( 0%) 140.9M ( 0%) But again, what - outside of me creating more inodes - would cause that to change??
