  • Possible SSD issues using as a PVR

    We are still investigating this one and I am reading up on a lot of different issues surround SSD use.

    From what I can gather TRIM is enabled by default in Libreelec, but I can't seem to find whether fstrim needs to be run periodically or not, does this need to be setup to aid in drive performance and reliability over time? Keeping in mind that as a PVR decently sized video files are regularly being 'recorded' onto it, then when watched deleted.

    The general use case is to have this PC powered on 24x7, so it doesn't get rebooted.

  • Possible SSD issues using as a PVR

    Thankyou for the info, we will definitely keep investigating.

    One question I still have (and I don't know if you have any ideas at all, but it's worth a shot), is we have seen more than once where a reboot will stop the drive from booting and it appears to not show up in bios, but after unplugging the computer from power completely and letting it cold soak for at least an hour it will then boot up as normal and work until the next failure.

    The big question I am trying to work out is why a reboot would not work, but a cold soak would get it back up and running.

  • Possible SSD issues using as a PVR

    We have a couple of Intel based NUC's (when a Celeron J4125 and 8GB of ram) and a 1TB Kingspec SSD.

    We started using these on Libreelec 10, with tvheadend and they are primarily used as DVR's with two dual USB tuners.

    Over time we have been seeing some of these machines have issues where the hard drive goes into read only mode, and I have attached some of the dmesg log from what that happened.

    Here is where it gets weird, at that point upon a restart one of two things can happen.

    1. A reboot and the machine starts up as normal.

    2. A reboot and the machine goes to the BIOS screen as it cannot see the SSD as a bootable drive.

    At this point what we have found is that by unplugging the power from the machine and leaving it off for at least an hour or so and it will boot ok, sometimes it needs to be left without power for longer, but almost all of the time leaving it unplugged for a period of time the machine boots normally.

    The thing is it hasn't happened on all the machines and it's very random. If anyone has any ideas it would be greatly appreciated.
