Derrikdj Posted June 23, 2020 Share Posted June 23, 2020 I am new to unraid & currently building my first setup. I have a pair of 1TB SSD drives for my cache poole with currently about 262GB used & 738GB free so far. I installed SSD Trim & scheduled it to run nightly at 1am. After the 1st run last night my VM stopped working and I am unable to open or write files in the cache pool. Fix Common Problems found the following errors: Unable to write to cache - Drive mounted read-only or completely full Unable to write to Docker Image - Docker Image either full or corrupted When I try to run my VM I get the following error message: Hook script execution failed: internal error: Child process (LC_ALL=C PATH=/bin:/sbin:/usr/bin:/usr/sbin HOME=/ /etc/libvirt/hooks/qemu BitTorrentVM prepare begin -) unexpected exit status 126: libvirt: error : cannot execute binary /etc/libvirt/hooks/qemu: Input/output error If I try to edit the VM I get the following error message: VM creation error cannot create file '/etc/libvirt/qemu/BitTorrentVM.xml.new': Read-only file system I tried to run a btrfs scrub but nothing happens and the scrub status is immediately aborted I've attached my diagnostic file unraidsvr-diagnostics-20200623-1037.zip Quote Link to comment

Derrikdj Posted June 23, 2020 Author Share Posted June 23, 2020 Temporarily moved cache drives to usb docking stations until I can free up more internal SATA ports. Cache Pool is working again. Thanks! Quote Link to comment
