We have cluster of 2 nodes (Windows Server 2012) with file server role. There is resource group configured under cluster which have multiple shared disks. As one of the disk is having file system error we want to replace it with a new disk (LUN clone of existing disk) we already have cloned LUN presented to server. Issue while doing it is:
- We took existing problematic disk offline from failover cluster manager
- When we remove same disk from resource group all other healthy disks goes into offline mode and get removed from cluster group.
We have checked dependency from file server role properties and it has no dependency on problematic LUN.
Thanks in advance.

I see a couple of potential issues here, let me try to target them one by one:
Two remarks about this:
chkdsk
on the new disk, but be aware of the fact thatchkdsk
can remove files in order to repair the filesystem.This could be that the other disks have a dependancy on the disk you just took offline/remove. This is highly unusual, only when you use mountpoints the disks should have a dependency to a disk which is representing the mountpoint. In case of mounted on drive letters, a disk should not have a dependency. Check your dependency report for each of the disks which went offline.
If you have further questions, please update your post (not in comments) and I will update this answer.
