This has me VERY concerned. I periodically do an "lsraid -A -p" to check on the status of my RAID partitions and starting this morning the command always core dumps:
[root@server root]# lsraid -A -p Segmentation fault
Doing an strace on that command results in this:
execve("/sbin/lsraid", ["lsraid", "-A", "-p"], [/* 30 vars */]) = 0

The interesting thing here is that I'm using two SCSI discs doing mirroring on three partitions. Why would it be trying to open "/proc/ide//sda/media", that path makes no sense??
This is my first experience with software mirroring under Linux so I'm at a loss on how to diagnose this problem. I'm not the type of person to reboot to fix it. I want to know what happened and fix the cause.
