Hi, Ost will be able to be operated in one ? I was testing with MDS x1 OST x1. But, It has been freezed.
How many are a minimum number of necessary OST? 2007/2/12, Daniel Leaberry <[EMAIL PROTECTED]>:
I'm running the 64bit lustre rpms on Centos 4u4 over a channel bonded (mode 0) pair of interfaces. After formatting the MDS I bring it up following the directions on the mountconf wiki. It comes up and looks fine. I then bring up one of my ost's (doesn't matter which one, I've tried them all.) and it connects just fine as well. I can mount a client and see my filesystem consisting of one ost. Any attempt to bring up a second ost results in the following message. mount.lustre: mount /dev/sdd at /var/mnt/ost02 failed: Operation already in progress The target service is already running. (/dev/sdd) dmesg on the mds shows this LustreError: The config log for lustre01-OST0000 already exists, yet the server claims it never registered. It may have been reformatted, or the index changed. writeconf the MDT to regenerate all logs.

I've tried that dozens of times with the same result. It also says the registration with the MGS failed. I don't know why since it obviously succeeded for the 1st ost on the same box. I've reformatted all the disks at least 5 times and I've reached a point where I have no idea why it won't mount the second ost. Any insight would be appreciated.
