Hi,
I have a problem regarding datastore extents issue.
Normally, I have one datastore provisioned from the local disk (300GB x 4 with RAID5), ESXi was installed on this datastore.
It's working fine for a while and last week I decided to increase the datastore capacity using "increase" button on the datastore, I added another iSCSI LUN into the datastore so the total capacity has increased, now the datastore combined with two storages (Local Disk + iSCSI LUN).
Unfortunately, there was a power outage yesterday which cause SAN storage down for a few minutes. I found the error in ESXi that our VM has a problem with VMDK file. In the datastore properties, iSCSI LUN was missing from the datastore, it used to has two storages (Local + iSCSI) but now there is only local disk as below.
Total Capacity = 1.79TB but there is only local disk which is 833.22GB
If I try to increase the capacity again, it shows the storage which is missing from the Extents datastore.
I'm not sure that if I go ahead next -> next -> finish. All my data will lose?
I use the command vmkfstools -P /vmfs/volumes/xxxx , it shows that device naa.6exxxx might be offline
How can I bring it online or manually put it back to the datastore?
Here is the VMkernel.log

Does somebody used to has this kind of problem?
