Space reclamation from VM guest



today i enabled Space Recl. for my managment group. Vmware can use it without problem. Nice:-). 


But I have question about guest in esxi. We have CentOS 6.x servers. Is here some way to enable "fstrim" in CentOS when storage is now supporting space reclamation?


Thank you

Re: Space reclamation from VM guest

don't know about centOS, but generally it requires a rescan of the storage LUNs by the OS so it can repopulate the LUNs listed features.  I'm a M$ guy and that generally required a disk rescan, but in practice I found it easier to just disconnect and reconnect for me, but I didn't have downtime issues to worry about when I made the transition.
