Hi,
I'm running ESXI 4.1 (260247), on a DELL R410, with a DELL SAS6/IR SATA Controller, with 2x 500GB SATA Drives.
Everything was running fine, but since one week, after some time, my datastore become inactive.
I can still connect to vsphere, but the datastore is shown as Inactive. VM appears to be still runing (No one is marked as Inactive), but I can't ping anyone, nor reach them using Console or SSH.
The only solution I have found is to restart the host (Which takes 30-40min, as it's trying to save the state of the VM, but seem's he can't, as the datastore is inactive.). Anyway, after 30-40min, the server reboot, and everything is running fine.
The datastore become inactive always during the night. During the night, I have a job that backup my mail server. Maybe, it's because of a high I/O of the disks, then the datastore become inactive, even if it's seems to be weird, as I had this job running for months without any problems.
I don't have anything in the logs, so a little hard to debug.
I tried rescanning VMFS Modules, Refresh Datastore, Scan the controller, but nothing works expect rebooting the host.
If anyone have an idea, it would be greatly appreciated, as I can't sleep to much last weeks, because I have to check if my server is still running every night...
Thanks !
