verify: fix verification of uncompleted or errored ios Stoo Davies reports: ------ I'm doing some powerfail recovery testing on a storage array over iSCSI. Host is RHEL 6.4 kernel 2.6.32-358.el6.x86_64. With fio 2.1.2 -> 2.1.4 the job file below rides through the disks going away, and continues I/O after they come back, without reporting any errors. With fio 2.1.5 -> 2.1.8 when the disks come back fio immediately reports a meta verification error. I captured a trace with an finisar analyzer, and can see that after the disks come back and the host logs back in, a read is issued for an lba which was never written to. Since I don't see verification errors outside of the powerfail testing, I suspect fio isn't correctly handling failed writes during the time the disks are unavailable. ------ The issue is caused by a change between 2.1.4 and 2.1.5 that started logging IO for verification at issue time, instead of at completion time. If the IO only partially completes or completes in error, then we need to adjust the verification unit so that we verify only what fio actually wrote. Signed-off-by: Jens Axboe <axboe@fb.com>

iolog: don't serialize the writing of all logs Serialize based on filename, so that independent logs can be written at the same time. If the logs are big, this can take a while to flush to disk. It's silly to have all jobs waiting on each other, when they could write their own logs independently. Signed-off-by: Jens Axboe <axboe@fb.com>

verify: always log IO in the order they are issued We currently log verify_backlog verifies when they complete, which means the sequence of verify and issue might be different. Change this to log in one spot, prior to issue, and track the completion state of the logged unit instead. This unifies the handling of verifies. Signed-off-by: Jens Axboe <axboe@fb.com>

Adds check for numberio during verify phase. Currently, fio checks the block offset number in a block's header during the verify phase. We add a check for the io number (numberio) to detect stale blocks. This check is performed only on workloads that write data, as those workloads know what numberio was written to each block. td->io_issues[ddir] = 0; was removed so that numberio does not get reset at each iteration; we want numberio to keep incrementing to reflect how many times the same data was written.

iolog: Logging blocksize in IOPS traces When saving bandwidth's with write_bw_log option, the last column provides the blocksize used during the run. When doing the same with write_io_log option, the last column was always set to 0 which is confusing when reading the log file later. This patch put both write_bw_log & write_io_log using the same semantic by reporting the blocksize for every sample.

Add log_avg_msec option By default, fio will note an entry in the bw/iops/lat logs for every IO that is completed. This quickly eats up a lot of disk space for long running jobs. By setting this option to eg 1000, fio will average the results logged over 1 second instead. This reduces the resolution of the log, but makes it more manageable.
