It is attached. 42% done and seems to be working fine, but for whatever reason I never had a problem with parity checks. It would freeze afterwards.
There are 128 sync errors and that seems very atypical when I think historically. Since the freezes I've had a ton of sync errors whereas before I would rarely have them and if I did there were only one or two. I don't know if that information means anything, but I just thought I would mention it.
I typically have zero, and I think any at all should be investigated. An unclean shutdown is a likely cause. In fact, this is why an unclean shutdown automatically starts a correcting parity check.
Your syslog shows that you have booted in SAFE mode, so that is working now. And it shows it started a correcting parity check due to an unclean shutdown, followed by a lot of messages about correcting parity.
So, all seems to be as expected for now.
