Then, logically, there is something different about this logical volume than the others. All of them reside atop the same volume group, atop the same two physical RAID6 arrays, correct? Since I'm not quite tired of playing dentist (yet): 1. Were all of the LVs created with the same parameters? If so, can you demonstrate verification of this to us? 2. Are all of them formatted with XFS? Were all formatted with the same XFS parameters? If so, can you demonstrate verification of this to us? 3. Are you encrypting, at some level, the one LV that is showing low performance? Cory: "The two arrays were added to a volume group and multiple logical volumes were created." 4. Was this volume group preexisting? Are there other storage devices in this volume group, or _only_ the RAID6 arrays? 5. Have you attempted deleting and recreating the LV with the performance issue? 6. How many total logical volumes are in this volume group? 7. What Linux distribution are you using? What kernel version? We are not magicians here Cory. We need as much data from you as possible or we can't help you. I thought I made this clear earlier. You need to gather as much relevant data from that box as you can and present it here if you're serious about solving this issue. I get the feeling you just don't really care. In which case, why did you even ask for help in the first place? Troubleshooting this issue requires your _full_ participation and effort. In these situations, it is most often the OP who solves his/her own issue, after providing enough information here that we can point the OP in the right direction. The key here is "providing enough information". -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
