Yes, sorry I should've been more clear. I have configured the multipathing using the multipathd using the bare-bone configuration, as it didn't have LSI/3Ware controller-specific preset in the devices {} block.
What I did was based on the [1] and in the end consisted of this (I thinned it down in the end trying to find the culprit) multipath.conf:
blacklist {
devnode "sda" # the boot disk
}
defaults {
user_friendly_names yes
}
multipaths {
multipath {
alias storage
wwid 3600050c000015400f3ae000009040000
path_grouping_policy multibus
}
}
multipath -ll showed everything OK, with both sdb and sdc (the same 24 x 3tb raid6 array) as active and ready.
However no matter what I did, the filesystem is getting corrupted in 3-4 hours of active usage...
