The system was running well for a while but lately we had a flaky disk in the RAID array which we replaced with a healthy one but suddenly the CLVM/GFS became unusable, we can mount GFS but while listing it recursively 'ls -R' it hangs with Input/output error, can't even access the c/LVM LUN rawly using 'dd' BUT we still can access the LVM PV devices using 'dd'. Reconfiguring the LVM volume as a local one and accessing it exclusively from one node doesn't make a difference.
