Firmware update of RN516 with two EDA500 failed
I had not updated my RN516 firmware since I added my two EDA500's. I just updated from 6.7.4 to 6.8.1 and it failed. The firmware loaded, but on reboot it did not boot properly -- it got part way a...
From the 6.9.1 Beta 1 release notes:
[Beta 1] Fixed a rare issue where a volume with multiple RAID groups may temporarily fail to mount after reboot.
That may have been the issue you hit. It was a race condition during boot time that has been possible to encounter since 6.7.0.
Since EDA500 volumes are so slow due to the fact that they use a single SATA port multiplier, they are intentionally kept out of swap. They are also kept out of the read list for the root volume.
Prior to 6.9.0, no attempt would be made to add failed disks to the root RAID array, as long as the data portion was still intact. Proactive root repair was added in 6.9.0.
Still nothing? Hey, I need to know what I should do when the time comes for the next update. Was this a fluke, or is there a fundamental problem? If it's a problem, are you going to fix it or do I need to do something to avoid it?

That does sound like a likely scenario, and I'm doubly at risk with two EDA500's. So, it may happen again when I finally go to 6.9.x, but hopefully not after that. It'll take a while before I'm sure, but I'll mark that one as most likely solved. Thanks for the reply.
