is the file system mounted ?

Hello Dynamox,

Here are some other outputs :

Following your comment, I consider the fs unmounted :

[nasadmin@nas_cs0 ~]$ server_mount server_2 fs_backup /backup

server_2 :

Error 4109: server_2 : fs_backup : is mounted on /fs_backup

[nasadmin@nas_cs0 ~]$

[nasadmin@nas_cs0 ~]$ server_umount server_2 fs_backup

server_2 : done

[nasadmin@nas_cs0 ~]$

After :

[nasadmin@nas_cs0 ~]$ server_mount server_2 fs_backup

server_2 :

Error 16: server_2 : Device or resource busy

mount uxfs rw /fs_backup 961=287 rw noscan triggerlevel=512 accesspolicy=NATIVE nolock

[nasadmin@nas_cs0 ~]$

With another fs :

[nasadmin@nas_cs0 ~]$ server_umount server_2 test01

server_2 : done

[nasadmin@nas_cs0 ~]$ server_mount server_2 test01

server_2 : done

[nasadmin@nas_cs0 ~]$

It works fine.

considering you already tried fsck , i would open a ticket with support.

Dear Sir,

Here is some details :

Could you suggest a solution ?

Best regards.

datamover failover/failback might fix it but i would first consult with support

I suggest to work directly with support on this

Hello raphlou 

The file system is not a multipath fs to mount it on various mountpoints. As for your issue while mounting the fs again, as rightfully suggested by dynamox , I would do a quick reboot of the DM and check or even failover/failback (same downtime needed for both).

Let me know how that works.

Hi Everyone,

I have similar kind of issue, Please share if you have any resolution for this

Dear Sir,

I didn't get any solution.

The system was out of warranty, but also end of support for DELL-EMC. (NS-80)

To call support and to open an out of warranty Service Request would have been too dangerous, without any idea of the total price, with no idea on the success.

I have sold to my customer 4 additional DAEs with 60 disks 600 GB 10K, and I have added these drives into the clar_r5_performance Pool.

Then the customer has restored all the data needed, in a separate File System declared for that.

A very long maintenance operation, but I have got the customer satisfaction, and also nobody was fired monday morning. :-)

Try the different commands specified in this post, I hope that you will get a solution.

Good luck.

Best regards.

Raphlou.

please open a service request and have support troubleshoot and fix
