Just been doing some raid testing, and this happened ... linux-lfqf:/dev # mdadm md/parity md/parity: 31.97GiB raid5 3 devices, 0 spares. Use mdadm --detail for more detail. linux-lfqf:/dev # mdadm --stop md/parity mdadm: Cannot open md/parity linux-lfqf:/dev # mdadm --stop /dev/md/parity mdadm: stopped /dev/md/parity Weird - why can it successfully stop it when passed an absolute path, but not when passed a relative path? When I did the first variant, I used tab completion, and then when I edited it I really did edit it, not retype it, so I can't see any way the two arguments could refer to different objects. Oh - and mdadm --version mdadm - v3.4 - 28th January 2016 ie stock SuSE leap 42.2 Cheers, Wol -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
