Hi everyone ,
How can we reclaim space in LUN, The reports says there is a capacity mismatch between the host and storage system. Is there a manual way or such commands that can reclaim space in lun because we don't have a snapdrive.
What OS Do you use? If you are using a redhat 6.x or ubuntu 12.x, type a fstrim /mount point.
ex> df -h
/dev/sdb /mnt -> cd / -> fstrim /mnt
To use fstrim, You must use ext4 format using mkfs -t ext4.
Its on a VM and the guest OS is windows.
We use the ontap powershell module. There is a space reclaim function in that module.
Windows Server 2012R2 will reclaim space automaticly
for non space reserved lun with thin-provisioned volumes VM/physical windows server - snapdrive space reclaimer works perfectly...
In case of space reserved luns... I have experienced volume getting full after space reclaimer is run. Anyone has any resolution to this problem ???
