[73729.568995] EXT4-fs (nvme0n1p2): Remounting filesystem read-only [73729.569077] EXT4-fs error (device nvme0n1p2): ext4_journal_check_start:61: Detected aborted journal [73729.573741] EXT4-fs error (device nvme0n1p2): ext4_lookup:1700: inode #917524: comm rm: iget: checksum invalid [73729.593330] EXT4-fs error (device nvme0n1p2): ext4_lookup:1700: inode #917524: comm mv: iget: checksum invalid The affected file is /var/backups/dpkg.status.6.gz It was cleanly shut down and powered off on the 22nd February, booted yesterday morning followed by another reboot a few minutes later. What worries me is the fact that corruption has happened - and if that happens to a file rather than an inode, it will likely go unnoticed for a considerably longer time. I think I'm getting to the point of deciding NVMe or the LX2160A to be just too unreliable for serious use. I hadn't noticed any issues when using the rootfs on the eMMC, so it suggests either the NVMe is unreliable, or there's a problem with PCIe on this platform (which we kind of know about with Jon's GPU rendering issues.) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
