Issues with encryption
thebang2 opened this issue · 6 comments
Installed OMV with debian-nas-stretch-18.069-armhf.img.gz und linux-image-3.2.96-3-nas5xx-armhf.zip on my NAS-542. Tried to crypt my Raid with Luks, but is not working:
As I understand, Luks0pen is waiting for udev:
--> cryptsetup.log.txt
# Udev cookie 0xd4d4ab0 (semid 32769) waiting for zero
Inside the udev log, the requist is visible. Look like it takes to long and is killed.
--> udev.log.txt
May 11 19:33:52 debian-nas systemd-udevd[275]: seq 923 '/devices/virtual/block/dm-0' is taking a long time
May 11 19:35:51 debian-nas systemd-udevd[275]: seq 923 '/devices/virtual/block/dm-0' killed
--> dmesg.log.txt

Is this a known problem?
I'm facing the same issue on my NAS542
I would start looking at smart data
[ 699.632272] Buffer I/O error on device dm-0, logical block 976691184
Well that's not a SMART issue. I can reproduce this issue on my NAS and the hard drives are brand new.

I can also reproduce this, even on external devices.
Thing is this in not an issue with the plugin most likely with cryptsetup. I see in one of the dmesg kernel 3.2.
The plugin just presents a front end to use cryptsetup to encrypt and decrypt devices. Add keys, delete keys view info etc.
Also that nas might have issues using the embedded CAAM crypto module as you can see users reporting here

Says there disabling might help but io performance will drop down.
There is also the option to try another cipher better suited for arm maybe, another cipher means format the device again.
