August 26, 200817 yr Parity check takes about 18 hours and runs automatically after a power failure or forced reboot. Can I be accessing the drive during this process? Read only or can I also Write? Thanks
August 26, 200817 yr You can read and write (at a penalty) while a parity check is in progress. Your performance may suffer, but it will still work.
August 26, 200817 yr Parity check takes about 18 hours and runs automatically after a power failure or forced reboot. Can I be accessing the drive during this process? Read only or can I also Write? Thanks Yes, you can access the drives, and read, and write. It sounds like you are running on an IDE based motherboard, or have it maxed out with very large drives for it to be taking 18 hours for a parity check. That seems too long for most installations. My 11 IDE disk, 2 SATA disk array takes about 10 hours, you will need to post a syslog for any further advice... otherwise it is like calling a mechanic on the phone and saying my car is making a funny noise... What is wrong? Once parity is calculated, you can even read and/or write to a failed or missing drive. (but please replace the drive as soon as possible, if a second drive fails concurrently, you will lose data) Joe L.
August 26, 200817 yr My system takes about 15 hours to do a parity check - 15 drives - a collection of 1Tb, 750GB & 500gb.
August 26, 200817 yr My system takes about 15 hours to do a parity check - 15 drives - a collection of 1Tb, 750GB & 500gb. Speed depends on the motherboard, the drives, and the disk controllers... and most importantly, if the drives are on the PCI bus or the PCIe bus. If just using a PCI bus, it will limit the speed. Most IDE/PCI based motherboards like mine get 15Mb/s to 17Mb/s. SATA/PCIe based motherboards can get up to 50Mb/s or more. see here: http://lime-technology.com/wiki/index.php?title=User_Benchmarks Joe L.
August 26, 200817 yr The webGUI shows 20,855 KB/sec - seems consistent. Not sure if this is fast or slow
