This is the third time in a week that this has happened.  I run SABnzbd and Sickbeard along with a number of packages (using UnMenu Package Manager) and every few days I lose access to the contents of the flash drive.  If I telnet I can execute commands but LS returns empty directories on the flash drive.  I thought it was the flash drive but as soon as I had the first problem I moved over to my backup USB pro2.key flash and same problem. 

 

I have offloaded as much writing as I could off the flash (Sickbeard does put some log info on the flash drive).  I can't imagine that this would happen on both drives, one of which hasn't been running for more than 3 days now. 

 

Either drive boots up fine and has no errors when I check them.  Any one have any ideas?

remove add ons until it starts working again?

Yeah I started by dumping a bunch including MYSQL... Will see how it goes...  Thanks.

If you look at your syslog, I bet you'll see that you're running out of RAM, and at some point the OS starts killing stuff.

If that's the case, you could try adding one disk outside the protected array and configuring unRAID to use it as swap.

 

How much ram is in your system?

Do you have a cache drive?

 

If so there is a way to set the cache drive up in an advanced manner where you have multiple partitions on it.

 

As long as partition 1 is reiserfs it will be used for cache.

Parition 2 could be swap.

 

Also, you could write your logs to a hidden directory on the cache drive instead of the flash.

 

Keep in mind, adding swap only goes so far. If you are filling up the root ram filesystem in some manner, then there is little hope of recovery once you start running out of ram.  The root filesystem will in ram will not swap out.

 

a tmpfs filesystem will, but initramfs does not.

 

There are times when I run a huge rsync, then notice I start having all sorts of memory issues after it.

I'll have to check the log next time it happens (hoping it doesn't with my changes).  I don't have a cache drive, and I do have 4GB of RAM.  I'm going to see it happens again and then take action if needed, thanks for all the recommendations.
