iscsiTarget (LIO) und vmware probleme
Hallo in die Runde,
ich hab hier ein seltsames Problem in meiner Umgebung und weiss leider nicht genau wer hier schuld ist, ob vmware oder LIO, daher poste ich das ganze erstmal hier.
Ich habe hier ein HA-Setup auf Basis von ZFS+Pacemaker/Corosync+LIO das ganze wird dann via iSCSI an VMware herausgereicht. Das funktioniert auch prinzipjell gut, aber eine kuriosität habe ich dennoch, die erste LUN (lun0) übersteht den HA-Wechsel ohne Probleme, heisst ich sehe sie in VMware nach wie vor und alles schicke, ABER die anderen beiden LUNs haben immer probleme, in der Regel endet das mit einem "inaccessible" seitens VMware, dann muss ich ne weile wurschteln und dann sehe ich diese auch wieder mit etwas Glück mittels "Assign a new Signature", dann das alte inaccessible storage unmounten löschen etc.. was echt ätzend ist.
Kann mir da evtl jmd sagen wo der Fehler ist?
die LIO-config sieht so aus:
targetcli ls
