How to determine fs name from disk name ?

Question

Guys,

i wanted to know how to find out what file system(s) resize on particular disk. I just deleted a file system and was expecting my disk pool available space to go up. It did not so i wanted to see what else resides on those particular disks. I tried every combination of nas_disk -info and nas_volume -info ..yet it still will not show my file system(s) names that reside on those disks. Any idea ?

Thanks

try -all as an option haven't played too much with it. Gives tons of details though.

One thing that comes to my mind is - you may use nas_fs -info -all command and then filter it out with the specified disk name.

However, since you have deleted the file system, the respective storage pool should increase by the amount of the file system. It should not be depended on any other file system on same set of disks.

Are you checking the pool size in CLI or in GUI? If GUI, you may need to refresh it - but I assume you are checking it in CLI - which should show you the correct size.

My 2 cents,
Sandip

Sandip ..have you used the GUI on CFS14 ? Watching the GUI refresh on CFS14 is like watching paint dry ....command line is the only thing i can use to manage this box , btw nas_fs -info -all worked great too ..i dumped its output into a file and used vi to search for my disk name. Thank you all

i am going to try nas_info ...these file systems were created back in the days when AVM was not available ..so i wonder if i need to delete something else (volumes, stripes) ?

Thanks McK for this - It came to my mind after I posted my message

Another option will be using GUI - go to Storage -> Systems -> Volumes

Select the property page of the disk volume and it will show all the file systems residing on aginst the Eventually used by : field.

Thanks,

However, did you get the space back? I guess, you
were right in saying that it is not part of any
storage pool.

i did not

...these two disks are part of the storage pool so they were created using AVM. There are a few more file systems using these disks. I probably messed up with my storage pool size numbers, but in the process i learn a new way to gather fs/disk information

I forgot that you are running it on a CFS 14 - but I should have recollected your earlier messages and thought about the same. But I was quite sure you are using CLI only

Nice to know that you used nas_fs command as well - but the .whereisfs tool is a no doubt a good one.

However, did you get the space back? I guess, you were right in saying that it is not part of any storage pool.

Cheers,

How did you determine the storage pool size?Have you used nas_pool -size pool_name -slice yesI think the '-slice yes' is important for your example

dynamox · Answer

Hi Peter, i did not use -slice since i was querying clarata_archive pool and -slice is used by default for clariion pools. Am i right ?Thanks
