fs is running ACLCHK
Hello,
We have a VNX5300 that's been serving as the host for two filesystems, NFS-1 and NFS-3, specifically for NFS usage.
Currently, we're facing an issue where NFS-1 has become corrupted. Attempts to delete it have been unsuccessful due to an ongoing ACLCHK process that seems to be stuck and prevents any modification. Despite rebooting the system twice, the ACLCHK process persists.
I was considering to migrate the data from NFS-3 to another location, then proceed with exporting the VNX5300's configuration. Following that, I'm considering reimaging the whole system and restoring its configuration.
My hope is that this approach will resolve the system errors we're encountering - would such action plan work ?
I have concerns about whether this will affect any existing system licenses. Will reimaging the system preserve our current licenses?
Also, I'm looking for a way to identify all the NFS client IP addresses currently connected to NFS-3. Is there a specific command that can provide me with this information?
Thx!
A.

Hello abuzzi,
Without knowing why your ACLCHK is not completing. It is hard to say that reimage will resolve your issue for sure without looking at some logs to see what all is going on. If you do a reimage then, you will need to get your license before you reimage as your license will need to be applied once a reimage is complete. Here is a link for how to get your license file. https://www.dell.com/support/kbdoc/en-us/000102991

Hello,
I have successfully migrated the data from NFS-3 to a different location, which now allows the entire VNX to be accessed without any fear of data disruption.
I then rebooted the system one more but the ACLCHK process still appear to be running.
I also attempted to start the system with only the four mandatory disks, hoping that the absence of the file system disks would prevent the ACLCHK from initiating, but this was not the case.
Before considering re-imaging the system (for which I currently do not have the installation software), I am contemplating either removing the underlying RAID (with the hope that the system would then clear the file system) or accessing the DME through the console (I understand it should be running a Windows server (?)) and then terminating the scheduled service. Unfortunately, the same dial-up "clariion" method succesfully used for SP does not seem to work for accessing the DME.
Any suggestion ?

Hello abuzzi,
I would try to destroy all raid configuration first and see if your ACLCHK error still resides.

Unexpected positive breakthrough today.
Having noticed that the NFS-1 was showing as "<unmounted>,<corrupt>" but also "filesystem is mounted, cannot delete" and that it couldn't be unmounted due to "is running ACLCHK" this morning, with no active services on the storage, I physically swapped the data mover servers server_2 and server_3.
To my surprise, NFS-1 is now visible, mounted, and accessible "uxfs,perm,rw". It still tells me that "NFS-1 is running ACLCHK," but I suspect that now it can finish successfully...
