Hi, I’m trying to use dmsetup to query specific devices rather than using `dmsetup ls --tree` and having to use some bash or scripting to pull out the specific device. Example below ; # dmsetup ls --tree root_vg-mqm_lv (253:7) `-mpath4 (253:4) |- (65:48) |- (8:192) |- (8:80) `- (65:160) root_vg-kdump (253:2) `- (104:2) root_vg-mqmerr_lv (253:8) `-mpath4 (253:4) |- (65:48) |- (8:192) |- (8:80) `- (65:160) root_vg-apps (253:5) |-mpath4 (253:4) | |- (65:48) | |- (8:192) | |- (8:80) | `- (65:160) `- (104:2) root_vg-var (253:1) `- (104:2) root_vg-inf (253:3) `- (104:2) root_vg-tws (253:10) `-mpath4 (253:4) |- (65:48) |- (8:192) |- (8:80) `- (65:160) root_vg-swap (253:6) |-mpath4 (253:4) | |- (65:48) | |- (8:192) | |- (8:80) | `- (65:160) `- (104:2) root_vg-root (253:0) `- (104:2) root_vg-cdunix (253:9) `-mpath4 (253:4) |- (65:48) |- (8:192) |- (8:80) `- (65:160) If I only wanted to look at root_vg-mqm_lv I want to just see
root_vg-mqm_lv (253:7) `-mpath4 (253:4) |- (65:48) |- (8:192) |- (8:80) `- (65:160) I can’t seem to find this flag within the command, does this exist ? Or can it be added into future releases? This would make scripting around the command a lot easier and would also make diagnosing where we have devices that are not utilising
multipath, as below ; root_vg-mqm_lv (253:6) `- (8:192)
