# Purpose

Storage provider for iSCSI block devices from the NAS.

# Notes

Used for applications that need to store a lot of data, but not over the NFS connection. Examples include metrics and logging storage.

# Issues

## Resizing the Prometheus disk

There is an issue resizing iSCSI disks. The following Github issue has instructions on how to manually resize if a permissions error is thrown.

https://github.com/democratic-csi/democratic-csi/issues/491#issuecomment-3778463893

- Exec into the iSCSI node pod for the node where the volume is being attached.
- Find the path where the volume is mounted, this should be in the error, and the disk name
- umount \<path>
- resize2fs /dev/\<disk name>
- Receive the error that the filesystem isn't clean, press y to optimize
- fsck -f /dev/\<disk name>
- Ensure the above comes back clean
- resize2fs /dev/sdb
- Restart pod that is mounting the disk
