I am getting a multipathd segfault when I have more than 26 devices, and the device names become 4 characters. (i.e. /dev/sdz is consumed and the next device is /dev/sdaa). I was trying to hook gdb to a core dump, but it keeps complaining that it needs device-mapper-libs-debuginfo, which I can not find. Can anyone point me to this? I built multipathd with -g turned on and did not strip it. Here is the last few lines of output when I run it as multipathd -v9 -d: Jul 04 05:01:26 | alpa-0x000080: discover Jul 04 05:01:26 | libdevmapper: ioctl/libdm-iface.c(1606): dm table alpa-0x000080 NF [16384] Jul 04 05:01:26 | *word = 0, len = 1 Jul 04 05:01:26 | *word = 0, len = 1 Jul 04 05:01:26 | *word = 1, len = 1 Jul 04 05:01:26 | *word = 1, len = 1 Jul 04 05:01:26 | *word = 1, len = 1 Jul 04 05:01:26 | *word = 1, len = 1 Jul 04 05:01:26 | *word = 65:160, len = 6 Jul 04 05:01:26 | *word = 1000, len = 4 Jul 04 05:01:26 | libdevmapper: ioctl/libdm-iface.c(1606): dm status alpa-0x000080 NF [16384] Jul 04 05:01:26 | *word = 2, len = 1 Jul 04 05:01:26 | *word = 0, len = 1 Jul 04 05:01:26 | *word = 0, len = 1 Jul 04 05:01:26 | *word = 1, len = 1 Jul 04 05:01:26 | *word = E, len = 1 Jul 04 05:01:26 | *word = 1, len = 1 Jul 04 05:01:26 | *word = 0, len = 1 Jul 04 05:01:26 | *word = A, len = 1 Jul 04 05:01:26 | *word = 0, len = 1 Jul 04 05:01:26 | alpa-0x000080: rr_weight = 1 (internal default) Jul 04 05:01:26 | alpa-0x000080: pgfailback = -2 (config file default) Jul 04 05:01:26 | alpa-0x000080: no_path_retry = 3 (config file default) Jul 04 05:01:26 | libdevmapper: ioctl/libdm-iface.c(1606): dm message alpa-0x000080 NF queue_if_no_path [16384] Jul 04 05:01:26 | pg_timeout = NONE (internal default) Jul 04 05:01:26 | alpa-0x000080: event checker started Jul 04 05:01:26 | sdaa path added to devmap alpa-0x000080 Jul 04 05:01:26 | discard event on /block/sdaa/sdaa1 Segmentation fault -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
