I still haven't found a cure for this, but here are a few things I've
tried:
- configure the adaptor to only use 80MB/s
- disable write caching in the adaptor
- build a kernel that has tagged queuing disabled for this particular
Seagate drive.
So far, no luck. I'm still getting file corruption.
Of the corrupted files I've looked at, here's where the corruptions
starts (rounded to the nearest MB).
192MB, 208MB, 496MB, 256MB, 0.9MB, 437MB, 905MB, 656MB, 576MB, 672MB,
512MB, 672MB, 400MB, 643MB, 752MB.
The 0.9MB corruption seems to be an anomaly amongst my anomalies - when
I was writing 100MB
files, I wrote thousands of files and never saw corruption. When
writing 768MB files, I'm seeing
about one file in seven get corrupted.
BTW, if someone wants remote access to help track this down, I can
oblige.
Cheers,
Marj
