filesystem deletion not allowed because it has checkpoints

Question

Hello all, I am trying to delete a filesystem that I migrated everything off of.  I want to repurpose it's space and step one is to blow it away.  It used to replicate to our DR site but I stopped replication and then deleted it from both the source and destination. So when I go to delete this filesystem I get an error message Delete file system vm1-sata. Operation is not allowed because file system has checkpoints. Severity: Error Brief Description: Operation is not allowed because file system has checkpoints. Full Description: No additional information is available. Recommended Action: No recommended action is available. For more information and assistance: 1. Log into http://powerlink.emc.com and go to Support > Search Support. 2. Use the message ID or text from the error message's brief description to search. Message ID: 13691191307 However if I putty in and run rs_ckpt vm1-sata -list ALL it doesnt show any checkpoints for me to try a nas_fs -delete ckpt_name. So how can I delete this filesystem?  I don't need it anymore.  Is my syntax incorrect? # fs_ckpt vm1-sata -list ALL id    ckpt_name                creation_time           inuse fullmark   total_savvol_used  ckpt_usage_on_savvol Info 26306752329: The value of ckpt_usage_on_savvol for read-only checkpoints may not be consistent with the total_savvol_used. id    wckpt_name               inuse fullmark total_savvol_used  base  ckpt_usage_on_savvol

Ok chat fixed it!

So replicaiton was deleted both source and destination, but for some reason the root chkpt's were not removed.

Learned from chat-

First you check the info for the specific file system nas_fs -i vm1-sata

in the ckpts it shows root_rep_ckpt_38_37335_1,root_rep_ckpt_38_37335_2

Then the command to delete them

/nas/sbin/rootnas_fs -d root_rep_ckpt_38_37335_1 -o umount=yes -ALLOW_REP_INT_CKPT_OP

/nas/sbin/rootnas_fs -d root_rep_ckpt_38_37335_2 -o umount=yes -ALLOW_REP_INT_CKPT_OP

Then look at the file system info again and under ckpts there are none.

Now the filesystem can be deleted!

fs_ckpt -list -all use /nas/sbin/rootnas_fs -delete

try /nas/sbin/rootnas_fs -delete root_rep_ckpt_38_37335_2 -o umount=yes

Probably some internal checkpoints from the replication left over Search the forum – I think we had that case recently

Thanks dynamox. My syntax was wrong, I forgot the dash before the word all.

$ fs_ckpt vm1-sata -list -all

id ckpt_name creation_time inuse fullmark total_savvol_used ckpt_usage_on_savvol

56 root_rep_ckpt_38_37335_1 05/27/2011-07:59:27-EDT y 90% 58% 58%

57 root_rep_ckpt_38_37335_2 05/27/2011-07:59:32-EDT y 90% 58% 0%

Info 26306752329: The value of ckpt_usage_on_savvol for read-only checkpoints may not be consistent with the total_savvol_used.

$ /nas/sbin/rootnas_fs -delete root_rep_ckpt_38_37335_1

Error 3101: root_rep_ckpt_38_37335_1 : filesystem is mounted, can not delete ro_servers=server_2

$ /nas/sbin/rootnas_fs -delete root_rep_ckpt_38_37335_2

Error 3101: root_rep_ckpt_38_37335_2 : filesystem is mounted, can not delete ro_servers=server_2

Now my question is, how do I resolve the filesystem is mounted error?

Ok I found it under mounts in unisphere. Deleted it and also su to root just in case you need root and now I get this:

# /nas/sbin/rootnas_fs -delete root_rep_ckpt_38_37335_1

Error 2225: replication internal checkpoint : invalid operation

# /nas/sbin/rootnas_fs -delete root_rep_ckpt_38_37335_2

Error 2225: replication internal checkpoint : invalid operation

$ /nas/sbin/rootnas_fs -delete root_rep_ckpt_38_37335_2 -o umount=yes

Error 2225: replication internal checkpoint : invalid operation

Nope, didn't work. Do I need to open up a support case on this? Hate to have to wait awhile to get this done :-(

If the GUI in Unisphere simply gave me the option to override the warning and automatically delete the checkpoints we wouldn't even be in this situation. Instead of a hard error it should be "Filesystem has checkpoints. Would you like to continue deletion? Deletion will also remove the checkpoints". A simple Yes or Cancel would have been appropriate. How do I get that suggestion passed onto developers?

open a chat session, that will be faster

Rainer_EMC · Answer

Yes – use support chat They will most likely provide you with an support only switch to force deletion
