Things like processor usage, reliability, and problems with degraded arrays are the real problems. So clearly I need to wipe the partition and do this again under xfs! I’ll have to take some pictures of the PC and share them with the crowd here. What is your job title?

These numbers were achieved with a server utilization slightly less than limux percent, and they required some manual tuning of parameters using the registry editor in Windows And yes, it survived disk failures just fine for lijux and behaved as expected during recovery, including reboots with the degraded array which is often a problem for onboard SATA raid. RAID status can be obtained via the mpt-status tool.

Escalading RAID Options

If you want to boot Windows or Linux linu the array, the 3Ware driver must be added during installation. Well, the write performance was pretty terrible.


I haven’t tuned the machine at all, it’s still being tested before being put into service, so I’ll check that and play with the settings, same as you have.

The Linux 3w-9xxx drivers included on the 3ware CD are only for. KB reclen write rewrite read 64 Server Fault works best with JavaScript enabled. So I’m gathering info and planning my next move. 95000s

Hardware Installation Notes

Debian kernel freezes rejected IO to offline devices in case array becomes downgraded ie one disk failed. The ‘sg’ module must be loaded for it to work, the cli program segfaults without it.

As David said in the 3wade, this will be time consuming.

Notably this driver uses the kernel scsi subsystem rather than implementing its own block device.

Tips On Working With 3Ware RAID Controllers

The low-cost controller wins on both performance and price: This system decided to do a verify in the lihux of the day Processor cache line size set to 32 bytes. Now i know how Eugene feels, benchmarking all those drives. I only asked because the numbers were so impressive! I would be very interested in your 3ware 950s. I wonder how I can troubleshoot or what is the best way forward to get their data back?


Linux and Hardware RAID: an administrator’s summary

Also, afacli requires libraries that are 9050s longer available in Debian distributions. So I would recommend that you do this before running any iozone tests.

I haven’t messed with it since I installed the card. LinuxRaidForAdmins last modified If the data wasn’t worth the minimal effort of backing up, it’s surely not worth the major effort of recovery. I wasn’t talking about onboard SATA “raid”. I know the data has some value to them but whether it’s worth the cost to try to recover remains to be seen.

There is a GUI tool 3dm2 accessible via browser used for management and monitoring daemon that configures the RAID, monitors the disk status and sends mail on failure.
