My MBL 3TB stopped working fine yesterday all of the sudden. From night to morning it was not reachable via Network enviroment, but was answering ping.
I managed to access to it via ssh, only after rebooting it. Because after a while being up, it becames again impossible to be accessed. I realized the CPU consumption was extreamly high… i even saw it reach 13.0+ So i decided to kill all deamons i saw running on top. So i renamed mediacrawler, tally and monitoreo.sh to stop system restart this services.
After all this and runnig e2fsck -y /dev/sda4 (no bad sectors found) device is reachable again via network. But now performance its really really slow. I cant copy several big files all together to MBL (like 4 o 5 files of 1GB each) cos speed decrease and decrease to rates as 2.5MB/s until if gives error like “MBL not available” when i normally was enjoying about 40MB/s as avg. If i copy the files one by one, after a very slow transfer rate files can be copied.
I m really lost about what to do next. I got feeling there is smtg comsuming all CPU and because of that performance its so low. Maybe updating firmware would help, but unfortunately i installed the latest like 2 weeks ago. So i cant replace it with a new one. (or dont know how to)
Im about to buy a new NAS, different brand of course, extract the disk manually from the case, connected to a computer and backup everything to new NAS. I know this is a really extream decision, but i really dont know what else i can do.
If anybody was in my situation before, and could solve it, i d really appreciate any help or suggestion to keep trying to make things work as fine as they were doing until yesterday morning.
Thanks a lot, and i appologize for my long post.
