Once the stick has been received, will configure it to mount at _/mnt/recording\_cache_

In the meantime, creating the directory and configuring TVHeadEnd to use it


-- BEGIN SNIPPET --

root@testpi:/home/pi# mkdir /mnt/recording_cache
root@testpi:/home/pi# chmod 774 /mnt/recording_cache/
root@testpi:/home/pi# chgrp video /mnt/recording_cache/

 -- END SNIPPET --

In the TvHeadEnd Web UI

- Configuration -> Recording
- Recording System path: _/mnt/recording\_cache_
- Container: Matroska
- Include Episode in filename
- Remove all unsafe characters from filename
- Replace whitespace in title with '-'
- Tag files with metadata
- Skip commercials

Grabbing the UUID for fstab the lazy way


-- BEGIN SNIPPET --

pi@testpi ~ $ ls /dev/disk/by-uuid/
3d81d9e2-7d1b-4015-8c2c-29ec0875f762  787C-2FD4

 -- END SNIPPET --

Want the recording directory to be ext4, so


-- BEGIN SNIPPET --

root@testpi:/home/pi# mkfs.ext4 /dev/sda1
root@testpi:/home/pi# ls /dev/disk/by-uuid/
3d81d9e2-7d1b-4015-8c2c-29ec0875f762  787C-2FD4  8a4c7e0f-c379-4e2e-a7f2-15f47cd4dd94
root@testpi:/home/pi# mount /dev/disk/by-uuid/8a4c7e0f-c379-4e2e-a7f2-15f47cd4dd94
/mnt/recording_cache/
root@testpi:/home/pi# df -h | grep recording_cache
/dev/sda1        57G   52M   54G   1% /mnt/recording_cache

 -- END SNIPPET --

Definitely got the right device node, so, update fstab


-- BEGIN SNIPPET --

root@testpi:/home/pi# grep recording_cache /etc/fstab
/dev/disk/by-uuid/8a4c7e0f-c379-4e2e-a7f2-15f47cd4dd94  /mnt/recording_cache    ext4   
defaults,noatime        0       1

root@testpi:/home/pi# mount -a
root@testpi:/home/pi# chgrp video /mnt/recording_cache/ -R
root@testpi:/home/pi# chown hts /mnt/recording_cache/ -R

 -- END SNIPPET --

Interestingly, the user _hts_ doesn't appear to be in the group _video_. Lets fix that
while we're at it


-- BEGIN SNIPPET --

root@testpi:/home/pi# usermod -a -G video hts

 -- END SNIPPET --

Test recording running at the moment, the episode being recorded should end in around 10
minutes so will check back in on it in a while

The recording shows as complete in the WebUI, and the filesize on disk is 323M. Plays back
perfectly when requested through TVHclient

Checking that the setup will survive a reboot


-- BEGIN SNIPPET --

root@testpi:/home/pi# reboot

 -- END SNIPPET --


*Following the Reboot*


-- BEGIN SNIPPET --

pi@testpi ~ $ mount | grep recording
/dev/sda1 on /mnt/recording_cache type ext4 (rw,nosuid,nodev,noexec,noatime,data=ordered)

pi@testpi ~ $ ls -ld /mnt/recording_cache/
drwxr-xr-x 3 hts video 4096 Nov  8 13:46 /mnt/recording_cache/

 -- END SNIPPET --

Started a quick test recording, file created on disk. Looks like we're good.
