[DragonFlyBSD - Bug #3091] swapinfo print major/minor number when device name too long

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3091 has been updated by liweitianux.

File dfly.swapinfo.devicename.png added

Hi, I just did several more tests to confirm this issue.  When the swap device name gets longer, the printed name by "swapinfo" will first be truncated, then the major/minor numbers is printed instead.

Please see the attached screenshot for my tests.


Cheers,
Aly

Hi, I enabled swap encryption by adding the "crypt" option to "/etc/fstab", therefore the auto configured swap device has a rather long name ("swap-<serno>.<slice><part>"), which seems, I think, cause problem for the "swapinfo"/"pstat" tool.  For example:

dfly# ls -l /dev/mapper/swap-WD-WCAS25235448.s1b
crw-r-----  1 root  operator   65, 0x1e11000f Oct 21 08:26 /dev/mapper/swap-WD-WCAS25235448.s1b

dfly# swapinfo 
Device          1K-blocks     Used    Avail Capacity  Type
/dev/#C65:0x1e11000f  16777216  1141708 15635508     7%    Interleaved
     ^^^^^^^^^^^^^^^

By default, "swapinfo" should print the device "name" instead of such major/minor numbers.


Cheers,
Aly
