Mountain Lion Compatibility
Is there any early word on Mountain Lion compatibility for the ReadyNAS models?
Spotlight "not working" at first may have been because it was busy rebuilding indices?
Anyway, I have my own issue:
I installed ML and then tried to access the NAS (a v1 NV+) only to be told by ML that the fileserver was not supported. Realised I hadn't updated RAIDiator in a while, and updated to 4.1.9. Success! At first glance everything works fine, but I have been getting some hard-to-debug lockups lately.
For instance I'll be copying batches of movie files from local disk to the NAS using Finder. Once I get up to 3 or 4 concurrent copies something will go crazy, and Finder will lock up with the spinning wheel. Leaving the machines to sort themselves out had no effect. First time this happened I ended up rebooting (via hard reset) the ML machine.
BTW this is a MacBook Pro connected by gigabit to the same Airport Extreme as the NV+. In case it's relevant, both machines have auto-negotiated Ethernet frame sizes (to 1500 bytes).
Then yesterday I was using Quicktime Player to convert some AVIs on the NAS to m4v files on local disk (for transfer to an iPad). In Snow Leopard I could queue up multiple files and it would do them in turn. In Mountain Lion it does them in parallel. I had two runnning and the machine was quite busy, but I went on to start more so I could walk away from the machine for a while. I started the third conversion and guess what happened? The spinning wheel, and Quicktime Player was no longer responding. Finder was a bit iffy too (at least one window was referencing the folder on the NAS).
Sighing, I started shutting down other apps so I could restart the machine. And then instead I decided to unplug the gigabit (also turned Airport off so it wouldn't fail over to it). Came back a while later and the NAS was unmounted, Quicktime Player was gone, and the machine was behaving normally. Reconnected the cable, remounted the NAS, and did AVI conversions one by one with no problems (although I didn't get them all finished by the end of the day as I had hoped to).
So, it smells like the NAS is failing with too many concurrent connections under load. Note that this setup has worked fine previously, and this machine (primarily being a photography workstation) regularly transfers huge amounts of data around during backups without missing a beat. This failure is new behaviour: the recent changes being a fresh ML install and a RAIDiator update. Recent backups (across various USB and Firewire disks) that don't touch the NAS have been fine (literally terabytes of data have been transferred in recent weeks due to disk reorganisations).
I'm setting up some more tests to try to isolate the issue (including testing concurrent access from another machine), but it's hard to get any detail when it locks up and it's obviously very disruptive to my work. Has anyone else seen similar issues?
