CIFS errors causing ugly Lag and eventually crashing!!
« on: December 19, 2008, 01:35:37 pm »
Ok,

So my new setup has been running for almost 3 months now, and in that time I only had to reboot my core for hardware changes. However just the other day, we had a power outage, and the system was in full swing, watching TV in the living room, girls watching videos in the family room, me playing audio in the basement. After the power returned, and running the mysql repair mythconverg for the crashed db, it seemed to work fine.

Now as of yesterday, the system is locking up. However it is only doing so when I boot my Living room MD.
The family room MD runs great, no errors are reported.
The living room gets about all the way booted up, and then I am seeing this on the core syslog:

Eventually the MD gets booted up, although painfully slowly, and then after it is up there is noticeable hanging by the entire box. So last night I rebuilt the MD, deleted the old one, then added a new one. It gets up as far as running through the sarah bits, and then it starts to hang again. This MD has 3 storage drives on it, 2 internal SATA disks, and 1 External Mybook.

I have 2 questions:

1. Does the core use CIFS to attach to these drives that are local to the MD.

2. Is there a way to re-install the CIFS/Samba server bits on the core, to see if it somehow got corrupted?

And the end all option is to re-install the core, which I do not really want to do, but will if necessary.

It seems that CIFS issues should be easily trouobleshot and resolved, however my googling has not payed off yet.

I ask for guidance in this issue, or experiences from other users out there.

Thanks, and Regards,

Seth

Seth - maybe you could start by determining whether it is definitely a CIFS issue root cause or if that is just another symptom, by switching to SMBFS instead? Definitely doesn't look healthy, its oops'ing...

change "cifs" to "smbfs" in all your file share devices and reboot everything.

Is it alright if I remind you now? Or is this fixed in 0810? :)
