I have a folder on my server that mounts volumes of a FreeNAS via the iSCSI protocol. I need to mount these same folders on another server but I can't figure out how they were mounted because the naming in FreeNAS and the folders are different.   Are there any commands I can use to see how they were assembled? Using the df command I have the following return:

/dev/sde       1008G  605G  352G  64% /mnt/folder1
/dev/sda       1008G  150G  808G  16% /mnt/folder2
/dev/sdf        4,0T  4,0T     0 100% /mnt/folder3

But this is not useful since I can't figure out which volumes these mounts are referencing.

I'm Using Debian GNU/Linux 8.9 (jessie) and FreeNAS 9.10.2.

  • Perhaps you could add details to your question. If the `df` output is from the backup server in question, it shows mounted folders on the right and physical storage devices on the left. You don't usually mount anything to a directory in a folder. – wick Dec 10 '19 at 16:09
  • These folders are mounting volumes of a FreeNAS. I need to mount the same folders on another server but I can't figure out which FreeNAS volume they are mounting. – Luis Sobotyk Dec 10 '19 at 16:19
  • Again, it doesn't make sense. The folders are mounted on `/dev/sdX` - they are scsi devices (sd) - not volumes. – wick Dec 10 '19 at 16:46
  • It actually uses the iSCSI protocol, which looks structurally like SCSI. – Luis Sobotyk Dec 10 '19 at 16:56
  • Ah I see. `iscsiadm` won't solve it for you? – wick Dec 10 '19 at 17:11
  • Oh, that was really helpful. It was not as I imagined but I managed to get where I wanted with `iscsiadm`. Thank you very much wick. – Luis Sobotyk Dec 10 '19 at 18:01

As we discussed in the comments to the original question, /dev/sdX is simulated devices with iSCSI protocol. To manage those you would normally use iscsiadm command.
