Hello, I'm new to multipath and I'm having an hard time configuring the one shipped with my distribution. The version is "multipath v0.3.6". If I insert aliases in multipath.conf and modify udev.rules I can see symbolick links wichi can be used in failover or multibus (tested) but they are not seen by the LVM2 (even modifying the filter in lvm.conf and specifying "types"). When I try the out-of-the-box configuration I get links in my /dev/block/by-id but they don't seen usable with multipath (applycation die). Any help on how I need to configure the multipath properly to work with LVM2? A multipath -v2 shows me the following: # # all paths : # 1IBM_____2105____________70623125 (0 0 0 0) sda [ready ] (8:0) [2105800 ] 1IBM_____2105____________70723125 (0 0 0 1) sdb [ready ] (8:16) [2105800 ] 1IBM_____2105____________60623125 (0 0 0 2) sdc [ready ] (8:32) [2105800 ] 1IBM_____2105____________60723125 (0 0 0 3) sdd [ready ] (8:48) [2105800 ] 1IBM_____2105____________50123125 (0 0 0 4) sde [ready ] (8:64) [2105800 ] 1IBM_____2105____________40423125 (0 0 0 5) sdf [ready ] (8:80) [2105800 ] 1IBM_____2105____________30423125 (0 0 0 6) sdg [ready ] (8:96) [2105800 ] 1IBM_____2105____________20423125 (0 0 0 7) sdh [ready ] (8:112) [2105800 ] 1IBM_____2105____________01723125 (0 0 0 8) sdi [ready ] (8:128) [2105800 ] 1IBM_____2105____________11423125 (0 0 0 9) sdj [ready ] (8:144) [2105800 ] 1IBM_____2105____________01823125 (0 0 0 10) sdk [ready ] (8:160) [2105800 ] 1IBM_____2105____________11523125 (0 0 0 11) sdl [ready ] (8:176) [2105800 ] 1IBM_____2105____________70623125 (1 0 0 0) sdm [ready ] (8:192) [2105800 ] 1IBM_____2105____________70723125 (1 0 0 1) sdn [ready ] (8:208) [2105800 ] 1IBM_____2105____________60623125 (1 0 0 2) sdo [ready ] (8:224) [2105800 ] 1IBM_____2105____________60723125 (1 0 0 3) sdp [ready ] (8:240) [2105800 ] 1IBM_____2105____________50123125 (1 0 0 4) sdq [ready ] (65:0) [2105800 ] 1IBM_____2105____________40423125 (1 0 0 5) sdr [ready ] (65:16) [2105800 ] 1IBM_____2105____________30423125 (1 0 0 6) sds [ready ] (65:32) [2105800 ] 1IBM_____2105____________20423125 (1 0 0 7) sdt [ready ] (65:48) [2105800 ] 1IBM_____2105____________01723125 (1 0 0 8) sdu [ready ] (65:64) [2105800 ] 1IBM_____2105____________11423125 (1 0 0 9) sdv [ready ] (65:80) [2105800 ] 1IBM_____2105____________01823125 (1 0 0 10) sdw [ready ] (65:96) [2105800 ] 1IBM_____2105____________11523125 (1 0 0 11) sdx [ready ] (65:112) [2105800 ] #
