I've removed one of the disks of a node for test purposes and added it again, now i am trying to collect informations on that activity, but what I find is just an indication about the time the disk was removed in the "Event" summary under "Alerts".
I repeated the test twice, excluding the disk through Prism GUI and, in the other case, phisically removing the drive. In both cases details about the event and subsequent activities are poor.
Further informations are needed to me, to better understand the behaviour of Nutanix in the case of a disk failure.
How I collect more informations about this test? Where I can find them?
Thanks in advance
~/data/logs/hades.out would be a good start
As always, feel free to open a support ticket and we can help guide you to the exact info you need.
Also, if we're lacking on logging or display GUI, we can file an enhancement off that support ticket, and integrate that feedback into the product. All goodness
All of our drives use SMART monitoring. If we see a disk about to fail, we will preemptively start migrating data OFF of the drive, in preparation for its replacement.
After you replace the disk, data will eventually rebalance on to the drive
Do you have to choose the new disk in Prism and select "repartion or add" or should it just come back online by itself with no intervention?
