Hi all,
I tried to install the Hosted-Engine on a FC lun, and the first time, it failed at the end because of a sanlock issue. So I fixed it and the re-deoployed from scratch until this new issue [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Physical device initialization failed. Please check that the device is empty and accessible by the host.]". HTTP response code is 400.
Before, I found that the lun [2] was used:
[ INFO ] ok: [localhost] The following luns have been found on the requested target: [1] 36006016039a142001792ac5b1b9e513a 1024GiB DGC VRAID status: free, paths: 8 active
[2] 36006016039a142006755b25b7505d26b 100GiB DGC VRAID status: used, paths: 8 active
So it was the good explanation for the failure.
Following the admin guide, I cleaned up the lun using
# dd if=/dev/zero of=/dev/mapper/36006016039a142006755b25b7505d26b bs=1M count=200 oflag=direct
And re-deployed it until it complains the device was not empty despite of before. The script still reported that the status of the lun was "used"
Finally, I rebooted the host, and that time the script considered the lun status as free.
So there is somewhere a bit of code into the ansible script that keeps the old status of the lun before dd, until rebooting.
Hello, for removing a volume i usually disable the logical volume (vgremove) and then the physical volume (pvremove). At this point i have the device marked as clean.
