Linux File System Fsck Testing — The Results Are In

“It has been a while since we started the fsck project to test
fsck (file system check) times on Linux file systems. The lengthy
delay in obtaining the results is due to the lack of hardware for
testing. The original vendor could not spare the hardware for
testing. A number of other vendors were contacted and due to
various reasons none of them could provide the needed hardware for
many, many months if at all. In the end, Henry used his diplomatic
skills to save the day, persuading Data Direct Networks to help us
out. Paul Carl and Randy Kreiser from DDN contacted me and agreed
to provide remote access to the hardware (thank you, DDN!). Paul
used a DDN SFA10K-X with 590 disks that are 450GB, 15,000 rpm SAS
disks. He used a 128KB chunk size in the creation. From these disks
he created a number of RAID-6 pools using an 8+2 configuration (8
data disks and 2 parity disks). “
