Back in September I got an email from my Drobo S saying a drive had been removed (which it hadn’t), followed by another saying my data was unprotected, another saying a drive was added.
I contacted Support and eventually after about 1 week got a response saying that there were problems with the drive in Bay 4. I rushed out and bought a new drive and replaced the one in Bay 4.
Everything seemed fine.
Today, I got a series of emails from my Drobo S
- Critical Drobo Alert: Drobo is Critically Low on Space
- Critical Drobo Alert: Drobo cannot currently protect your data against hard drive failures.
- Drobo Warning: Data protection is in progress, but you may continue accessing your data. Do not remove any hard drives.
- Drobo Notification: Drobo detected a new drive was added.
Obviously I’ve raised a support question, and included the diagnostic log file.
However I have 3 questions/comments:
It seems to be a big failing of the Drobo Dashboard that it doesn’t allow me to find out which drive is causing the problems (it took a week last time to reach the stage of Drobo Support telling me which drive was causing problems). I want to know NOW so that I can replace the drive and minimise my risk of data loss.
It seems odd that 2 drives should fail in a short time. Apart from a few hard drives that have been DOA (presumably damaged in transit) I’ve never had a hard drive fail (before they’ve got too old I’ve usually replaced them with larger capacity drives). Getting 2 in 3 months fail (at this stage I’m assuming) seems more than just bad luck.
Why did the Drobo tell me I’m critically low on space? My Drobo S is has 5.85TB capacity, I have a 4.3 TB partition used for Time Machine (which has 4GB free) and another partition which is empty and shows a capacity of 13TB.
