So the coding for this change really did take just five minutes (https://github.com/mulkieran/pyblk/commit/03acb3d60369514e9b98676eaa2798d547f58df0). And the new results look something like this. DEVNAME DMNAME DEVTYPE DIFFSTATUS SIZE /dev/nvme0n1 None disk None @372.61 GiB `-/dev/md127 None disk None @372.49 GiB |-/dev/dm-29 vg-cache0_cmeta disk None 16.00 MiB `-/dev/dm-31 vg-lv_tdata disk None 32.00 GiB `-/dev/dm-32 vg-lv-tpool disk None 32.00 GiB |-/dev/dm-33 vg-lv disk None 32.00 GiB `-/dev/dm-34 vg-thin1 disk None 1.00 TiB ... Is that what you were getting at? If you wanted to have the DMNAME override the DEVNAME whenever it was available that would take another five minutes. (I like to know where my data is coming from, so keeping them separate suits me). - mulhern > > > > _______________________________________________ > > cockpit-devel mailing list > > [email protected] > > https://lists.fedorahosted.org/admin/lists/[email protected] > > > > - mulhern > _______________________________________________ > cockpit-devel mailing list > [email protected] > https://lists.fedorahosted.org/admin/lists/[email protected] > _______________________________________________ cockpit-devel mailing list [email protected] https://lists.fedorahosted.org/admin/lists/[email protected]
