Sync iSCSI on connections from two different PCs

riahc3 · Post by **riahc3** » 30 Jun 2015 11:39

I connect two different PCs to the same iSCSI on NAS4FREE and I créate folders one PC, it doesnt appear on the other. I can also créate the same filenames and no conflict or anything.

How can I get them to sync and appear on both size whenever there is a change?

Allowing multiple hosts access to a single target is an exceptionally bad idea.
Doing so can lead to all manners of problems, including data corruption.

Thank you for your warning but I still wish to do it.

How can I set it up in NAS4Free? From what I understand I might need a clustered file system which I dont mind formatting by current volumen to.

I am not really familiar with iSCSI' s internals, but from what I believe, it is not something you can setup in N4F's end.
It is the client that needs to have a filesystem which will support what you want to do.
I might be wrong, though, so please don't quote me on this...

are you really sure that you need Block Level Storage instead of File Level Storage?

if you want to go that way you need a cluster file system like OCFS2 or GFS, otherwise concurrent writes of different machines will destroy your files.

Yup. Its the only way I can access the file from two different places at the same time.

I have doubts on which of file system to choose for that...

You are not describing your scenario correctly. NFS., Samba, ftp and AFP let you do that we'll.

You right, I'm sarcastic.
1 iSCSI target for 2 or more initiators is no good idea. Target must be multipath device, you must have 1 NIC per initiator.. I not listen anything about support multipath for iSCSI target.
