Hi,
I just recently got a bunch of HC550 18TB non-sed 512e/4k SATA drives. I wanted to convert these to 4k/4k for use in ceph. So I went on my merry way and downloaded hugo and did;
Code:
./hugo f -b 4096 -m WUH721818ALE6L4
Now this turned out to be a bit of a mistake as it started formatting all 12 drives in the server in question. Which initially was fine, but the format took forever, and unfortunately I lost ssh connection to the server and hugo subsequently crashed. Only later I learned I should have used --fastformat.
A good 24hr later, I powercycled the server. And now, unfortunately none of the disks seem to work anymore. I can still see then with hugo s:
Code:
# ./hugo s

But they are unresponsive in regards to formatting them, and if the MegaRAID controller tries to configure them as non-raid devices, they are immediately marked as failed until reboot.
Trying to format one yields the following result:
Code:
# ./hugo f -b 4096 --fastformat --danger-zone -s 3RG71UXA
Format device on 1 Device(s)...
Failed: Format command Failed on device 3RG71UXA.
Device will not be formatted.
Any advice at all would be greatly apprechiated.
Thanks!
Best,
Rune
