The following sections describe scenarios where an instance might encounter capacity issues and provides steps to help address the problem.
"No space left on device"
Check if the Filestore instance has sufficient inodes by running the following command on the client VM:
df -i
The command returns something similar to the following:
Filesystem Inodes IUsed IFree IUse% Mounted on
10.0.0.2:/vol1 134217728 13 134217715 1% /mnt/test
Each file stored on the file share consumes one inode. If IUse% reaches 100%,
you are not able to store more files on the file share even if you haven't
reached the maximum allocated capacity. The number of inodes scales with
capacity. If you want to add more inodes, you must add more capacity.
The following service tiers have a maximum capacity usage of approximately 89% of the provisioned capacity. The remaining capacity is reserved for internal operations and resources:
| Service tier | Maximum capacity usage limit? |
|---|---|
| Basic HDD | Does not apply |
| Basic SSD | Does not apply |
| Zonal with a lower capacity range | Yes |
| Zonal with a higher capacity range | Yes |
| Enterprise | Yes |
For details, see Known issues.
df and du commands report different amounts of free disk space
When a file that is open by a running process is deleted, the disk space that
the file consumes does not get freed until the file is closed. The df commands
accounts for the space consumed by deleted open files, whereas the du command
does not. This difference in calculation is why the du command often shows
more free space than df.
To display the deleted files that are still open by a running process, run:
lsof | grep deleted
