Hi everyone, I’ve been trying to add a SSD as persistent cache device for my two HDDs:
zpool add -o ashift=12 zfs-14tb-1 cache /dev/disk/by-id/ata-Samsung_SSD_850_PRO_256GB_S251NXAGB66384X-part1 -f
zpool add -o ashift=12 zfs-14tb-2 cache /dev/disk/by-id/ata-Samsung_SSD_850_PRO_256GB_S251NXAGB66384X-part2 -f
Which works fine and in zpool status the specific partitions of the disk/by-id/ device get attached to the respective pools. However after a reboot the -part2 device always gets renamed to “sde2”. I’ve tried removing the cache device and re-adding it but that only fixed the device name until I rebooted.
I know this is not really important, but it’s kind of weird why it works for -part1 but not for -part2. Is this a bug?
I’m using open-zfs on gentoo linux, initially had the sys-fs/zfs-kmod-2.1.9 but I then upgraded to 2.1.11 and 2.1.12 and tried removing and re-adding it but this did not change the result. Kernel was 6.1.x initially, now 6.3.x with the new openzfs version.
