first aid volume could not be unmounted imac

Does anyone have any insight into why we would be getting so many zombie processes? Every time I want to remove a datastore we are running into this problem. The only way to clear them out is to reboot the host.

Sh: can't kill pid 33601: No such process The problem is these are all zombie processes and cannot be killed Working with VMWare support we were able to list out the processes that are hanging onto that datastore. These datastores I'm cleaning up are either VMFS3 or VMFS 5.54.ĭoes anyone have any ideas on why these won't unmount? So I am looking at a month before all the cleanup can be finished in our current state. We also have very strict rules regarding host reboots and they can only be performed in the evening. Although this is getting to be quite annoying considering I have 30 datastores to cleanup and cannot continue on the next datastore until the one I'm working on is completely unmounted and then re-purposed. Right now the only resolution has been to reboot the hosts that are having a problem. I have also tried unmounting them from the command line and by connecting to the hosts directly with the vsphere client. I also ran lsof and could not find any files in use on that LUN. All VMs have been migrated off, the datastore is not used for heartbeat, vsantraced is disabled, SIOC is disabled, it is not apart of a datastore cluster, and the coredumps have all been cleared. Correct the problem and retry the operation.īut there are not anything on the datastore in use.

The error that is occurring indicates that the file system is busy.Ĭannot unmount volume 'Datastore Name: Hosted_FC_LUN70 VMFS uuid: 5202965c-e09a124d-9e1b-001a64c85540' because file system is busy. It is not always the same 3 hosts it varies. So we are sVmotioning VMs off some datastores then deleting the LUNs.įor every datastore we are cleaning up there about 3 out of 16 hosts won't unmount the datastore. We are going through doing some cleanup on our datastores.
