I followed this guide to install writecache https://wiki.omv-extras.org/do…:omv8_plugins:write_cache
On my dashboard it says writecache not running in red.
It is enabled with Use system memory, flush on shutdown and rotate on shutdown all enabled.
Writecache Plugin

While I recommend not using System memory, the system does have an occasional issue trying to enable the mounts because files are in use. The mounting typically happens when the system is booting before services are running. Have you rebooted?

May be a small bug
Unfortunately, without any logs, i don't know what it did wrong. If you attach /var/log/omv-writecache.log, I might be able to tell.

I had the same issue (WriteCache not running. I've rebooted at least 5 times.
To resolve the problem...
SERVICES > WRITE CACHE > DISABLE > SAVE > ENABLE > REBOOT

SERVICES > WRITE CACHE > DISABLE > SAVE > ENABLE > REBOOT
This is just running the saltstack again. I still recommend not using System memory.
Hopefully fixed in 8.1.4 in the repo now.

I appreciate your reply. Unfortunately, being a OMV/Linux newbie, I have no idea what either of your sentences mean. Ha! But that's MY problem, not yours.
Coming from the Windows world, I'm doing my best to get up to speed with OMV/Linux as quickly as possible, but, geez, there's an awful lot to absorb. And, to be honest, it's not that easy. The Linux documentation & tutorials I've encountered so far only get a C- in my opinion.
I have a feeling you may be the head guy in the OMV hierarchy, so thank you for all your work and time. Best regards.

saltstack if the configuration management framework that writes config files and makes changes to the system.

votdev is the founder and dev of OMV. I created omv-extras and its plugins.
The issue you ran into should be fixed in the latest release of the writecache plugin.

New user (almost) currently doing research before my nas box arrives so am reading about the write_cache plugin.
My system will boot via m.2 drive so I think I need the plugin running? Why do you recommend not using System Memory and what *do* you recommend? Thank you.
P.S. One of the first things I read was the FAQ at OpenMediaVault FAQ and it still references the deprecated flashmemory plugin. That probably should be updated so new users like myself aren't unecessarily confused.
QuoteWhat should I use as a system drive?
If flash media is used, installing the openmediavault-flashmemory plugin is strongly advised. Debian as well as OMV are writing and reading almost constantly on your system drive. Therefore, if you do not install the flashmemory plugin,you will burn the chip on a USB stick in no time... Alternately, you can use old notebook HDD´s. Any drive size you have available. Note that the drive will only be available for the OpenMediaVault system. You cannot use it (also not partly) as a data drive by default. You can also use a USBtoSata converter or an external USB HDD. You can, of course, build standard drive of your choice (HDD or SSD).

It isn't required for nvme but I do run it on my systems with nvme.
Why do you recommend not using System Memory and what *do* you recommend?
I don't recommend using System Memory because a power outage will cause all file changes since last sync to be lost since files are stored on tmpfs (system ram).
I recommend unchecking the System Memory checkbox. This will show you a shared folder dropdown and then you would store the files on a data disk.

Which guide is that? The omv-extras new user guide is referencing writecache - https://wiki.omv-extras.org/doku.php?id=omv8:new_user_guide

Also, the FAQ I mentioned is here on the forum at OpenMediaVault FAQ
I didn't remember that post existed. It is ancient. I unpinned it.
