The issue seems to be that the current default for max_sectors_kb is too high for our setup:
$ cat /sys/block/sde/queue/max_sectors_kb 32767 Cutting this in half resolved our issue: $ sudo sh -c 'echo 16384 > /sys/block/sde/queue/max_sectors_kb' We made this permanent by adding a udev rule: $ cat /etc/udev/rules.d/61-block-max-sectors.rules ACTION=="add|change", KERNEL=="sd[a-z]", SUBSYSTEM=="block", DRIVERS=="qla2xxx", RUN+="/bin/sh -c '/bin/echo 16384 > /sys/block/%k/queue/max_sectors_kb'" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585668 Title: Random file corruption when writing large files to hba mounted volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1585668/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
