~# btrfs scrub status /dev/sda2
scrub status for 4aeb8f2b-ed97-476b-858e-2a73b7698499
scrub started at Thu May 28 11:17:27 2015 and finished after 18 seconds
total bytes scrubbed: 3.77GiB with 0 errors
both btrfs and zfs have checksums for data and metadata, so the likelihood of the checksum being corrupted in exactly the right way to coincide with the random corruption of the data is exceedingly low, unless I'm being hacked by someone who proved P=NP and has exploited that to trivially crack hash functions like md5
the zfs scrub is going now, but I doubt it'll find anything, since the original crash was due to a btrfs error
~# zpool status -v z

and I trust ZFS's scrub even more than I trust btrfs's
I think what happened was a transient in-memory corruption with btrfs
basically, it tripped over itself while doing something in the kernel data structures, but never wrote out that corruption to disk
@Bob right, but "don't use Linux" translates to "don't successfully use hundreds of open source programs that only compile cleanly on Linux and maybe Windows and BSD, but not Solaris" (unless you VM Linux, but eh)
Linux = compatibility with code I need ZFS = reliability and performance I need hardware RAID = CPU offloading of parity calcs I need btrfs = I could easily replace it with something else, but it's there, so meh lxd = container isolation I need (though Solaris/SmartOS containers work great, too)
Not just on the same network. We only mark questions as duplicates if they are on the same site, e.g. a question can exist on both SU and SO wihtout being marked as duplicates. See: What to do with cross-site duplicates?
You can comment with a link to that other site, if you want to. If you wish...
Yeah. That's why I want to answer by rephrasing his. Just making sure it's a valid answer. You were talking about how it's from the programmers side. Didn't want my answer to be too skewed.
@Bob you could quite easily just use linux-md software RAID-5 and deal with the RAID write hole when it comes (and it would definitely !!zalgo COMES sooner or later; power failure, kernel panic, whatever)
everything you need for linux-md + xfs is built into the kernel and it can install / and /boot on it no problem
> Recent GRUB releases assume that the /boot/grub/grubenv file is writable by the stage2 module. Until GRUB gets a ZFS write enhancement, the GRUB modules should be installed to a separate filesystem in a separate partition that is grub-writable.
ha
that was 2012, no idea what the status is now
they also included some hacks to work around it (remove some lines of script that write there)
but that's if I can't get the EFI stub working
it gets me into an ZFS-compatible prompt... just won't auto-mount and boot :(
And it is wonderful. 36 different endings. Your decisions matter. I called out some priest that was hating on me and 10 hours later he sent guys after me. I was like "What the hell? I did that ages ago?"
I take a good long time to make a decision. Especially with the woman. Currently it's not going well. I told them both I love them because I didn't want to hurt their feelings. Sometimes the game can be a jerk and force you to make quick decisions.
@bob yeah, I don't know how much it was intentional, and how much it is because I and other guy sit past a corner and the rest of the team sit together
Or maybe because I silenced the unnoficial Telegram group that's supposed to contain urgent work stuff but is 75% inane stuff

After I learned about the service, I've seen a lot of people using it at home, work and their phones

I kind of like the Macro Workbook approach in a shared directory, so that users will always have the updated version, as opposed to the file in your %APPDATA%, but still the macro should be easy to access. I guess there's always View -> Macros -> ...
But then, every time you run a macro, that pop up menu closes.
oh cool, there's an Organizer menu from Macros that let's you copy modules over.
Hi, I'm wanting to count the number of commas over many texts, on windows, I've done find /c "," *.txt but it lists the count per files, I'd like the total sum
heh... Called a user that had a job logged about some software that wasn't working correctly. Apparently the software fixed itself, but then she mentioned that her desktop has been randomly restarting multiple times a day for about a week.
