Data Backup and Recovery
Hi,
We have SQL cluster with two nodes. We have lun of 1000 GB and we unable to expand the lun any further. There is enough space in the volume but the snapdrive doesn't recognize the available space and doesn't and we are running Snapdrive 6.5.0.5474 on both the nodes. Are there any limitations with the version of snapdrive we are running? I believe this is latest version available for download on Netapp site. Please advise.
Thanks.
Hi ,
Can you please provide the status of the volume which holding this lun like
volume current usage (df -g ) , vol status ,vol options and if that volume is also holding any other lun ?
Thanks ,
Ashwani
Surprised if this doesnt work in the latest release of SnapDrive!! As Ashwani asked. whats the output of df-g for the affected volume
Filesystem | total | used | avail | Capacity Mount |
/vol/volXXX_data0/ | 3328GB | 2347GB | 980GB | 71% |
/vol/volXXX_data0/.snapshot | 0GB | 413GB | 0GB | ---% |
Above is df -g output for the volume.
Hi ,
Sorry for not asking the below things 1st time .
Please also provide the ">vol option volume_name " output & details of other lun if any in this volume
Thanks
Ashwani
Could you post the output of "lun show -v <lun name>" for the LUN's in the SQL cluster
Thanks
I dont think there are any other luns in the volume. Below is the output. Thanks for the response.

Well, I found this article. And the Maxsize of the lun it set to 1 TB. Is there a way to change the max limit for the lun?

Hi deshaw. Please run the following coomand:
lun maxsize <path>
This should give an output like this:
lun maxsize /vol/LS_ESX5i_SC01_DATASTORE_vol
Space available for a LUN of type: solaris, aix, hpux, linux, netware, vmware, openvms, xen, solaris_efi or image

Looking at the outputs below you have space guarantee's at the volume level and your fractional reserve also set at 100%
I dont think there are any other luns in the volume. Below is the output. Thanks for the response.

if you put the CLI in diag mode, you can run a LUN Geometry and this will tell you the max size that the LUN can be grown to, example:
lun geometry /vol/LS_ESX5i_SC01_DATASTORE_vol/LS_ESX5i_SC01-DATASTORE
SCSI Disk Geometry:
512 bytes/sector
2048 sectors/track
16 tracks/cylinder (heads)
32768 sectors/cylinder
9600 cylinders
314572800 sectors
16777216 cylinder size (16 MB)
161061273600 device size (153600 MB)
1099494850560 max resize size (1048560 MB)
If you can grow your LUN further, then you need to amend your Fractional Reserve and Guarantee settings.

Is the lun has been grown to ten times its original size ?
This is what im thinking and that if it has, then a new LUN will have to be created.
