[VNX5300] Error 4425: server_2 : fs MIC-NFS-1 is running ACLCHK

Hello,

I'm currently dealing with a corrupted filesystem that I need to destroy and subsequently recreate. Unfortunately, I've encountered an issue where the system reports that an active ACLCHK is preventing the operation of server_umount.

I have attempted to resolve the issue by powering down the VNX, hoping this would terminate the ACLCHK process, but no luck there.

Could you provide guidance on how to kill the ACLCHK process and proceed with unmounting, destroying, and recreating the filesystem?

Thank you,

A
