Hi, all I used multipath-toosl 0.6.4 for some testing. When executing udevadm trigger command, I find something wrong with multipathd. Logs are as follows: Mar 15 19:26:00 server155 multipathd: sdj: path wwid changed from '360002ac000000000000000e700013071' to '360002ac0000000000000002600013071'. disallowing Mar 15 19:26:00 server155 kernel: [706183.837704] multipathd[1165440]: segfault at 198 ip 0000555f6d022607 sp 00007f1f992f5960 error 4 in multipathd[555f6d018000+18000] After parsing the address with objdump, I think uev_update_path accessing null pointer pp->mpp . Call trace maybe: uev_trigger uev_update_path dm_fail_path(pp->mpp->alias, pp->dev_t); Has anyone ever met it and how to fix it? Thanks!
