The G4L files boot just fine, but it is a smple kernel and initramfs boot. Doesn't use UUID or other things. Changed fstab to make sure all blkids match from partitions. Machine 103 has duplicate partition except for the /home partition. > There's no such thing as "minor things" when it comes to filesystem > corruption, especially when it results from a power loss. > > Your filesystem suffered unknown corruption and damage.

Even now the system has outages. On this notebook, I create a full disk image of drive about once a month. My G4L takes the 1TB boot drive /dev/sdb and creates a raw image file of about 70G containing all the data of partition in about 30 minutes. sfdisk -l /dev/sdb Disk /dev/sdb: 953.87 GiB, 1024209543168 bytes, 2000409264 sectors Disk model: Fanxiang S101Q 1 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 70647742-8953-40B3-8BDE-1C14F7B6D51B Device Start End Sectors Size Type /dev/sdb1 2048 1230847 1228800 600M EFI System /dev/sdb2 1230848 4376575 3145728 1.5G Linux filesystem /dev/sdb3 4376576 192071679 187695104 89.5G Linux filesystem /dev/sdb4 192071680 1590808575 1398736896 667G Linux filesystem /dev/sdb5 1590808576 2000408575 409600000 195.3G Linux filesystem Latest image file. 68640583757 Apr 26 16:35 /data2/sdb-zst-test2.zst Looks like time to create a new one.
