Package: zfsutils-linux Version: 2.0.1-3 Severity: normal Dear Maintainer,
on a host where the ZFS installation is based on harddisks, the /usr/lib/zfs-linux/trim cronjob triggers e-mails with the body | cannot trim: no devices in pool support trim operations The reason for this is fairly obvious. Still these messages create nothing but noise. Please find a solution for this - preferably by checking beforehand whether trimming is possible. Or if all else fails, by muting stderr from the "zpool trim" command. Although that might hide serious errors as well.
