Regarding memtest, normally in Linux I have never been able to run it from inside an installed Linux system because it needs access to protected kernel memory, and instead it has to run from a live USB or from the memtest86 live testing image. But since this system is a proprietary NAS with uboot and no video interface I don't know how to run a memtest. > To be extra safe, please provide the dump of your UUID tree: ------------------ root@OpenMediaVault:~# btrfs ins dump-tree -t uuid /dev/sda3 btrfs-progs v5.10.1 uuid tree key (UUID_TREE ROOT_ITEM 0) leaf 170459136 items 4 free space 16151 generation 366 owner UUID_TREE leaf 170459136 flags 0x1(WRITTEN) backref revision 1 fs uuid 4a057760-998c-4c66-aa6a-2a08c51d5299 chunk uuid 54b2fa0f-9907-49d1-af33-e172581cd25e item 0 key (1101835439474057344 EXTENT_ITEM 56168916570538915) itemoff 16275 itemsize 8 item 1 key (0x0f4a817e92c9a080 UUID_KEY_SUBVOL 0xc78d54ff9b03a3a8) itemoff 16267 itemsize 8 subvol_id 5 item 2 key (0x421cfa6924ef510d UUID_KEY_SUBVOL 0xc8423812cf31288b) itemoff 16259 itemsize 8 subvol_id 269 item 3 key (0x45a64f82bc9152f1 UUID_KEY_SUBVOL 0x3859efe8688d6ea4) itemoff 16251 itemsize 8 subvol_id 274 total bytes 1990110658560 bytes used 704343715840 uuid 4a057760-998c-4c66-aa6a-2a08c51d5299 ------------------
