[DragonFlyBSD - Bug #3207] swapon fails silently when trim option is given

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3207 has been updated by deef.


If I read the code correctly, given device is first turned into a crypted volume, then "trim" operation is performed on the volume, and only when this succeeds, swapon() is called actually.

The problem may be that calling ioctl() with DAIOCTRIM argument on a crypted volume just fails. If that's the case, an error message "Device trim failed" should be displayed, followed by usage() which ends with exit(1).

Bug #3207: swapon fails silently when trim option is given

In /etc/fstab I have the following line:

/dev/serno/xxx.s1b none swap sw,crypt,trim 0 0

When I startup, "swapctl -l" does not list any devices.
If I remove the "trim" option above, it works and "swapctl -l"
shows the configured device.

The disk is a Samsung SSD 960 PRO using the nvme driver.

Having no swap configured silently might not be the best option.
