Due to the current usage patterns on Bridges-2’s Ocean filesystem, an inode allocation has been established. It will be enforced in addition to the storage quota for your grant. The inode allocation is proportional to the size of your storage quota, and is set at 6070 inodes per GB of storage allocated.
Inodes are data structures that contain metadata about a file, such as the file size, user and group ids associated with the file, permission settings, time stamps, and more. Each file has at least one inode associated with it.
Inode quotas are set on your project directories in the Ocean file system. There is currently no inode quota on home directories in the Jet file system.
To view your usage on Bridges-2, use the
my_quotas command which shows your limits as well as your current usage.
[user@bridges2-login013 ~]$ my_quotas The quota for project directory /ocean/projects/abcd1234 Storage quota: 9.766T Storage used: 1.384T Inode quota: 60,700,000 Inodes used: 453,596
Tips to reduce your inode usage:
- Delete files which are no longer needed
- Combine small files into one larger file via tools such as zip or tar
