Package: zfsutils-linux Version: 0.8.6-1~bpo10+1 Severity: important Dear Maintainer,
The recently added cron "TRIM the first Sunday of every month" makes some SSD drives crash. The problem appears on reasonnably busy and otherwise stable servers: * with about 100 containers, * each on a separate zvol, ext4 mounted with discard option, * on a 6 identical drives raidz2. The issue has been observed on these drives: * Micron_5100_MTFDDAK960TCB * Samsung_SSD_850_EVO_1TB * Samsung_SSD_860_EVO_1TB When affected (it not always the case), the systems could not complete the cancelling of the trim with: # zpool trim -c pool Testing trim on one drive only, and reducing the rate to as low as 500000, did not help. A reset seems the only solution, followed by a zpool trim -c after reboot. It would be wise to deactivate that cron by default, or at least to provide some kind of convenient way to do so, like an option in /etc/default/zfs. Thank you. -- System Information: Debian Release: 10.8 APT prefers stable APT policy: (900, 'stable'), (500, 'stable-updates'), (400, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 5.4.19 (SMP w/8 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8), LANGUAGE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages zfsutils-linux depends on: ii libblkid1 2.33.1-0.1 ii libc6 2.31-9 ii libnvpair1linux 0.8.6-1~bpo10+1 ii libudev1 241-7~deb10u6 ii libuuid1 2.33.1-0.1 ii libuutil1linux 0.8.6-1~bpo10+1 ii libzfs2linux 0.8.6-1~bpo10+1 ii libzpool2linux 0.8.6-1~bpo10+1 ii python3 3.9.1-1 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages zfsutils-linux recommends: ii lsb-base 10.2019051400 ii zfs-dkms [zfs-modules] 2.0.2-1 ii zfs-zed 0.8.6-1~bpo10+1 Versions of packages zfsutils-linux suggests: pn nfs-kernel-server <none> pn samba-common-bin <none> pn zfs-initramfs | zfs-dracut <none> -- Configuration Files: /etc/default/zfs changed [not included] /etc/zfs/zfs-functions changed [not included] -- no debconf information
