Package: lvm2 Version: 2.03.22-1+b1 Severity: normal Dear Maintainer,
snapshots of cached volumes seem to be seriously broken (maybe it's fixed in the latest upstream version, I'm not sure). To see the issue, try the following: * create a cached volume, make a ext4 filesystem in it, mount it, and put some contents there so the FS isn't empty; * start some process making changes to the volume (like cyclically copying files etc, which imitates a busy filesystem); * create a snapshot of the volume; * try to check the snapshot with fsck. With non-zero probability you will get filesystem errors on the snapshot. (Note that if you do the same on a non-cached volume the check passes as it should.) Trying to fix the errors automatically and then removing the snapshot will most likely lead to the ruined filesystem on the volume. I learned this the hard way when I tried to e2scrub my cached /home partition. Granted, I have backups... -- System Information: Debian Release: 12.5 APT prefers stable-updates APT policy: (991, 'stable-updates'), (991, 'stable-security'), (991, 'stable'), (99, 'testing'), (90, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.6.13-bootes0-p-1000 (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_WARN, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_DK.UTF-8, LC_CTYPE=en_DK.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en_US Shell: /bin/sh linked to /usr/bin/dash Init: sysvinit (via /sbin/init) LSM: AppArmor: enabled Versions of packages lvm2 depends on: ii dmeventd 2:1.02.196-1+b1 ii dmsetup 2:1.02.196-1+b1 ii libaio1t64 0.3.113-8 ii libblkid1 2.38.1-5+deb12u1 ii libc6 2.36-9+deb12u7 ii libdevmapper-event1.02.1 2:1.02.196-1+b1 ii libedit2 3.1-20221030-2 ii libelogind0 [libsystemd0] 246.10-1debian1 ii libselinux1 3.4-1+b6 ii libudev1 254.5-1~bpo12+3 Versions of packages lvm2 recommends: ii thin-provisioning-tools 0.9.0-2 lvm2 suggests no packages. -- Configuration Files: /etc/lvm/lvmlocal.conf changed [not included] -- no debconf information
