So i had my drobo running fine for a bit but then all of a sudden i started to hear a vibrating sound coming from the drobo that i could stop by removing the front panel from the drobo or by gently pressing on the drobo casing. I assumed as both drives were working it was the drobo fan. So i removed the drives and the fan is fine it didn’t vibrate so it must be one of the drives. I put them back in and booted it up. When i replaced the panel once the drobo had booted up (which i did gently) the bottom of the two drives disappeared from the system, bringing about the red light, green light combo on the remanning drive and the relayout procedure (see my feature request to stop this issue). (pressing on the drive didn’t remount it either).
Note: at one point the drive also dismounted within the drobo without any interaction. I forgot to mention this before.
So i left it to do the its work. The next time i put the cover back on it proceeded to dismount all the drives system shut down.
I am not sure what to do at this point, is the drives faulty or the drobo. Should i post the log on here. Suggestions/answers appreciated.
