August 12, 201411 yr Hi, I am struggling with one issue, and can't get it solved... I have added one new disk (precleared, then formated in main menu, etc, etc) and it works properly - i can access it through my share. However if i reboot unRaid, then it's not in protected array anymore. System finds it, but it's not there....i added itagain, reformatted, etc. After reboot - not in array again... Can anywone help me in the right direction to solve this issue? Thanks! unRAID Server Plus version: 5.0-rc8a Disk 5 (/dev/sdb) is not in array after reboot.
August 12, 201411 yr It is not clear without a syslog, but my suspicion is that the USB flash drive is being mounted read-only which is why the settings are not sticking. I would mount the USB drive in a PC and run checkdsk on it (or the equivalent on a Mac). Hopefully this will report it has fixed an issue and your problem will be resolved. If the problem persists then you will need to provide a full syslog so that it is possible to see what is happening.
August 12, 201411 yr Author How do i change the read/write properties of USB flash drive? the server is remote and i can access it only through terminal or lan/web management Edit: i have checked the file/folder properties in the boot folder and boot/config - seems like full permissions...

That will show if the USB stick is being mounted read-only (which would explain your symptoms). As to how one fixes that without physical access to the server I have no idea although I suspect it should be possible. Running checkdsk against the USB stick is normally recommended as with physical access it is very easy to do. There should be a Linux way of doing the equivalent, but it would have to be done with the array stopped so that the USB stick can be safely unmounted for checking, and I am not sure of the correct command sequence. You may of course have some other issue, although nothing obvious springs to mind.
August 12, 201411 yr Author I have attached the full syslog (i took it from /var/log/syslog, right?) Hope this helps.
August 12, 201411 yr Looking at the syslog, I can see the entries: Aug 11 22:57:58 MOVIESERVER kernel: FAT-fs (sdf1): error, fat_free_clusters: deleting FAT entry beyond EOF Aug 11 22:57:58 MOVIESERVER kernel: FAT-fs (sdf1): Filesystem has been set read-only This shows that as I suspected the USB stick is being mounted read-only which explains your symptoms. As to how one can fix this in-situ I have no idea - you will have to wait and see if one of the Linux gurus can suggest how this might be done.

Well i can get access to NAS directly, but not now, some other day... So if i get to it, i take out the USB flash and put into my home PC and run disk check? In other words, this flash may be corrupt/broken/faulty?
August 12, 201411 yr Thanks. Well i can get access to NAS directly, but not now, some other day... So if i get to it, i take out the USB flash and put into my home PC and run disk check? In other words, this flash may be corrupt/broken/faulty? Yes. More often than not it is a corruption (perhaps caused by something like a power cut) and running checkdsk fixes it. If it keeps re-occurring then it can be an indication that the USB disk is failing in some way. I am hopeful that someone may post a way to do this from the Linux command line without the need to remove it from the server. In fact I may do some research myself on this today as that would often be preferable to opening up the server as the mere fact of doing that can sometime disturb connections leading to other issues.
August 12, 201411 yr Author Maybe fsck might be useful? http://www.thegeekstuff.com/2012/08/fsck-command-examples/
August 14, 201411 yr Author Ok so I got to NAS, removed usb flash, put it into Windows PC and ran disk check (with option 'auto-fix' enabled). It did find errors and fix them. Then put it into NAS and cleared/reformatted new Disk again and after reboot everything works properly. Thanks for the help again.
