HA-Yellow: Nextcloud and its own nvme: proof of concept

[senna1992]

Hi there,

this is my journey:

the goal? i want to host my cloud myself.
the basics? homeassistant yellow with m.2 ssd and cm4 with emmc.

the obstacles?
running nextcloud ootb it stores everything inside of the emmc - and therefore bloats the HASS backups.
running HASS on the same partition as nextclouds data storage - a crash could cuase huge data loss.
every upload runs through the emmc ootb, so it crashed my smarthome for about 2 days repeatedly.

my result:
installed the m.2 nvme preformatted to ext4.
installed nextcloud on the pi and added the ssd to the addons config under local disc.
changed the temp directory used by nextcloud (using docker to access the containers console).

How to do it?

• First get a good grade ssd (i got western digital RED because they say it is rated for nas usage)
• make it ext4 and create two folders (data and temp)
• grab the /dev/name using "advanced ssh terminal" addon and command "lsblk -f"
• drink coffee
• setup nextcloud, mariadb (the nc protocol view shows what to enter as server for your mariadb)
• edit two config files (see below) within the container (/data/config/php/www2.conf and /data/config/www/nextcloud/config/config.php)
• run chown abc:abc /path/to/your/tempfolder
• run chmod u+w /path/to/your/tempfolder
• restart
• check folder size (growing) with du -h -s /path/to/your/tempfolder while uploading something using the pc/mac client.

What to add inthe mentioned files?

1. config.php: add 'tempdirectory' => '/path/to/your/tempfolder',
2. www2.conf: add

• env[TMP] = /path/to/your/tempfolder
• env[TMPDIR] = /path/to/your/tempfolder
• env[TEMP] = /path/to/your/tempfolder

now it should work and spare your precious emmc
