There is just 1 thing that worries me. VO1 is the only disk I'm able to use to retrieve data from (in the NAS). If i put only O1, N1 or both, I'm not able to retrieve data from interface or export. No folders or anything. RAID is DOWN, Disk Usage = N/A. I suppose somehow the raid manager chokes in O1 and N1. If you plugin…

AFAIK the firmware is supposed to clone the partition table of the remaining raid member. So when doing your 1,2 strategy disk N1 will not get a GPT. I think the best approach is to put only N1 into the box, wipe the partition table dd if=/dev/zero of=/dev/sda bs=1M count=1 reboot, to get the non-existing table active,…

On my NSA325 I had the problem that after several days of uptime the whole TCP/IP stack died. Tried to investigate it using the serial port, but it was simply not reproducible enough, so I never figured out what caused it. It was not software related, as the software hadn't changed in years. I don't think it's hardware…

Is this working now? Yes, the forum at https://zyxel.diskstation.eu/forum/viewtopic.php?t=24 and the repository at http://zyxel.diskstation.eu/Users/Mijzelf/zypkg-repo/ are working. Is this update needed Define needed. If everything works for you, it's not needed. and is it possible to only have the NAS to be seen on…

That's weird. I see no real reason why this wouldn't work. I wouldn't expect the 'Avail Dev Size' to be different on both disks. The new one is supposed to be a clone of the old one, including partition table. But AFAIK this shouldn't be a problem for the raid array. You won't be able to enlarge this array to 4TB, when you…

This is one of the cases where "if you have to ask, it's not for you" can be applied. This box has a 3 stage bootloader. The CPU has some loader code build in, which is just smart enough to read and execute code from SPI flash. This is the 2nd stage 'uloader' you see. The uloader does some initialisation, and then loads…

no idea why I only can see three of them, and not the most important one… Did you have to login to access the network location? If not, you might be using a guest account, which of course has no access to the admin share. As a work-around you can use ftp. Enable ftp access for the shares you want to access, then you can…

How are you trying to access the NAS using explorer? Typing \\<ip-of-nas>\ in the address bar should always work. I'm very close to ripping out the HD and trying to connect it directly to the PC, but don't know if that's even possible. Yes, that is possible. But not using a Windows system. Any Linux distro should work.…

@mc_tech Can you enable the ssh server, login over ssh, and post the outputs of cat /proc/partitions cat /proc/mounts cat /proc/mdstat su mdadm -E /dev/sd[abcd]3

There is a disk in slot 2 at the moment? And you also had another disk in that slot? The disk is not seen at all. It's device name (/dev/sdb) is in use by the disk in slot 3. I'm afraid either the SATA port or the power supply in slot 2 died.

I'm not sure it makes much difference, they all seem to be the same. It does. The JBOD array (in more common words linear array) is a virtual 12TB disk, from which the first 4TB is on the first disk, the second on the second disk, and the last on the 3rth disk. So it is like you had a physical 12TB disk, containing a…

A tool like PhotoRec can recover files from bare metal without help of the filesystem, as long as they have a recognizable header, which also somehow tells which size the file has, and the file is not fragmented. Drawback are that any metadata from the filesystem is not recovered. No path (including the filename itself) or…

Can you post the outputs of cat /proc/partitions cat /proc/mdstat cat /proc/mounts su vgdisplay

Well, at least you have some filesystem errors, which can cause the zero byte files. You should run e2fsck on /dev/md2. Unfortunately that is not that simple. Here I wrote about how to get that done. The forum software has b0rked up my code, so you'll have remove the html code around and between the commands. And skip the…

So far the disks seem healthy. And your raid array contains a logical volume group, instead of a filesystem. To mount the internal filesystem execute vgscan vgchange -ay mount /dev/dm-0 /mnt/mountpoint Maybe /dev/dm-0 has to be /dev/dm-1 or /dev/dm-2. Don't know what is inside the volume group. lvdisplay might tell. About…
