I have a MBWE II 2TB (Blue Ring), 2 year-old, rarely used, mirrored device.
I have done the following few weeks ago:
- original FW (01.01.18) upgraded to 2.00.18
- enabled SSH
- installed ipkg
- installed nano
- installed transmission
Everything seemed to be fine (working), but few days later, suddenly I noticed that about 2 hours of operation after turning on, leds start alternate blinking showing that there is a critical disk problem. Before the problem occurs, the web interface shows that drive status is OK, but after it everything hangs and the MB is unreachable (even cannot be pinged).
I think I should check somehow that it is really a disk problem. I don't know what kind of disk problem can it be when the drives are usable for a given period, but after that they are turning bad. Any idea?
Are there any logs that might help me, or should I turn on something that can log what happens and check that after the next crash?
There is a post "hangs hard drive" (http://mybookworld.wikidot.com/forum/t-228881/hangs-hard-drive#post-731921). Maybe my problem
is similar, I will check it.
If there is a real disk problem, then I would replace one or both drives. Fortunately, the MB is nearly empty, there's no precious data on it, so only the system things are interesting for backup. I have found that there is a MybookClone Feature Pack, and that can be used to manage such a drive replacement. However, it is not clear for me: "Backup your Mybook's system partitions and synchronize your data automatically to an external USB/SATA HDD. In case of HDD failure, simply replpace your Mybook's HDD by the external one!. You can also use this feature pack to upsize easily your Mybook to a bigger disk…". How can I decide which internal disk is the bad one? It there something more to do if the replacement disk is bigger than the original? (I understand that if I buy the new disk from the same vendor, I will have no problem with the S15wdc-heat-monitor script.)
Any idea might help. Thank you!
