It sounds that these mount points have been created due to sort of replications or NDMP Snapsure backups. However, 1) By Default, Deleting (umounting) the mount points from the Unisphere GUI will automatically use -perm option which will permanently delete the mount points and decrease the counter for the total mounts (in this case, you should not have any problem when you use the GUI - you will not reach the maximum number of mounts 2048). 2) By Default, Deleting (umounting) the mount points using CLI will use -temp option which will keep the mount point available with status (will NOT decrease the counter for the total mounts)... you can verify it using server_mount server_2 command. 3) As long as you have the original FS or checkpoints available, no harm to delete/umount the mount points using -perm option (if you want to mount any FS or checkpoint in the future you can do so by creating new mount point!). 4) Since you have reached the maximum # of FS Per DataMover Blade 2048; you will not be able to create new FS on the same blade. you might be able to create it on a different DataMover Blade until you reach the Max # of FS per VNX 4096.  you can go and re-run the umount command but include the -p flag  a) backup the original FS mounts status (in case if you want to mount any FS with the old mountpoint name)  server_mount server_2 > /original_mounts.txt  b) server_mount server_2 | grep -i " " | awk '{print $1}' | xargs server_umount server_2 -perm  This will filter the FS based on the status and umount them using -perm flag (server_umount server_2 -perm FS_NAME). or you can use excel to manually filter them ... good luck [IMAGE]
I have been trying to create a new file system on our VNX5800 and it keeps telling me that we have exceeded the number of mount points for server_2. I've done a bit of digging around and found with the output of a server_mount server_2 | wc -l there are 2082 mountpoints. However 371 are showing as unmounted (These were mounts created by the checkpoints which we have unmounted).   [nasadmin@ c0 ~]$ server_mount server_2 | wc -l  2082 [nasadmin@ c0 ~]$ server_mount server_2 | grep unmounted | wc -l  371  So my question is when you do a server_umount on a file system does it not actually free up a mount point because by my simple logic if there are 2082 total mounts and 371 listed as unmounted we are well below the maximum of 2048 mounts per data mover so i am failing to see why i cannot create a new file system/mount point.  Am i missing something obvious here? Any help would be appreciated.
Too many mount points?
