Failed Drive Replacement

[Jocko]

You just need to use exactly the same name for the share as the folder name.

But you can not do this on the technical share (tr-daemon and tr-downloads) as these names are reserved.
if you do not have some torrent files on downloading, you must re-install transmission

[hvymetal86]

I had active torrents running at the time of the firmware update. I just checked its web interface and its up and working properly. It looks like there's a newer version though. If I stop it, upgrade, and then restart it will the upgrade wipe out my settings and active torrents?

[Jocko]

Install or update transmission client will remove the torrent files.

So do

Code: Select all

mv /share/1100/tr-daemon /share/1100/tr-daemon.org
mv /share/1100/tr-downloads /share/1100/tr-downloads.org

Install again transmission (do not start it)

You should see two new folders (tr-downloads; tr-daemon) in /share/1100.
So overwrite them by the original folders

Code: Select all

mv /share/1100/tr-daemon.org /share/1100/tr-daemon
mv /share/1100/tr-downloads.org /share/1100/tr-downloads

[hvymetal86]

Awesome thanks! I'll be doing that and re-creating the shares tonight and will update again once done. After that comes the drive replacement.

[hvymetal86]

Shares were all successfully recreated, transmission was updated w/o losing the settings or active torrents list. I'm now ready to do the drive replacement.

Hi hvymetal

Nice!

Now the next step should be easy. (I assume you did not install on some partitions a kernel image)
So:
- stop the nas
- put in the middle slot (sdc), the new disk
- start the nas
- go the setup disk
Then:
Either the new disk is listed on the disks/volumes and then click on the related link "reset" to initialize the disk
or if it is missing (<=> no partition table on the disk), click on the button "Initialize Hard Disks and Volumes". Then the new disk should be listed (and so select it to initialize it)

On both cases you need to select the partition table (=> gpt table with a disk size 3TB) and as fs : ext3 or ext4 (It does not matter as it will be included later in a raid)
After this step, a partition table should be created and also a single data volume

Then the last step is to include the new single volume (Vol-C) in your degraded raid volume.
Still from the disk setup menu:
- click on the link of your raid volume (which opens the edit volume menu)
- on the raid section, to repair your raid, select the new single volume (Vol-C) to add it on the raid

That's all

[hvymetal86]

I first tried resetting sdc using "GPT" and "ext3" settings. Chose ext3 just because the RAID volume is that for consistency, even though it doesn't matter once added to the array.

After adding sdc it is showing recovery status in Disk Setup initially:

Code: Select all

clean, degraded, recovering completed: 0.0%, estimated time: 3149.5min

And then a few minutes later it showed (slow) progress:

Code: Select all

clean, degraded, recovering completed: 0.2%, estimated time: 3194.1min

Something I noticed in the changelog for 17.0 and again in the edit menu of the RAID array is ext4. Can I use the convert feature (obviously after the RAID is healthy again) to convert the format type from ext3 to ext4 WITHOUT losing data? Thought of this because of the benefits the changelog mentioned.

[Jocko]

Hi hvymetal

:thumbup

Otherwise I expected a faster recovery speed :scratch but may be low if you have many I/O accesses on the disk. (maybe transmission is running or something else)
Can you post again

Code: Select all

cat /proc/mdstat
dmesg

Amazing you failed to use ext3. I need to see if we use the right command for large disk (>2TB)

Something I noticed in the changelog for 17.0 and again in the edit menu of the RAID array is ext4.

yes it is here you may convert the raid fs to ext4

[hvymetal86]

Transmission was running (set to autostart). I stopped it manually and then refreshed the GUI at the shown intervals to show change over time:

Code: Select all

clean, degraded, recovering completed: 12.9%, estimated time: 2637.9min

clean, degraded, recovering completed: 13.0%, estimated time: 2693.7min

clean, degraded, recovering completed: 13.1%, estimated time: 2537.4min
+7 min real time
clean, degraded, recovering completed: 13.3%, estimated time: 2677.6min

After those data points I ran the commands you requested:

Hi

Use 10k/s as max speed limit is useful only when the raid is reshaping (with a faster speed, you lose all access on the nas: you have some memory allocation errors which kill successively the running servers: apache; samba; dropbear;...) but on a recovery state you can use a bigger value. (I need to fix that on a next patch).

So restore the default value

Code: Select all

echo 200000 >/sys/block/md0/md/sync_speed_max

wait a few seconds and you should read a faster synchronization speed

Code: Select all

cat /proc/mdstat
