Hi readers,
In the last 2 years, I have upgraded from 4.11 to 9.2 then 9.3
releases, and since upgrading to the 9 series, I have experienced
endless data loss - every time I reboot my computer, massive numbers
of files vanish - 20 - 50 - a lot. And it's driving me crazy.
I don't expect to get any fixes here, but something is wrong
with the code - it's happening on ATA drives, USB flash drives,
a few of each kind. So, it's definitely not a hardware problem.
I wrote about this 2 months ago or so, and was advised to run
a utility on my hard drives - and the utility showed some wear,
but this is happening on USB sticks and cards as well, and
has nothing to do with old ATA drive wear.
I searched Google for data loss on FreeBSD, and I see that many
others have this problem as well. After 20 years, I am not keen
on switching away from FreeBSD, but the data loss is just killing me.
Every day, I am losing dozens of files. I am backing up, but that
is not the best solution, because it's easy to backup and mirror
the data loss as well, and it's a pain to constantly have the
stress of not knowing if critical files exist or not, and
constantly matching directories/archives to see which are complete
and current.
FreeBSD forums blocks my access, possibly because I don't have a
high-speed connection, so I can't read the material there. Sometimes
the loss is on newly created/saved files, sometimes on ancient files,
sometimes on ATA, sometimes on USB. I can't find any pattern, other
than it always happens on a reboot, and it seems slightly worse
with SoftUpdates+Journaling.
I know this is not an easy thing to analyze, but I never ever
had these problems with 4.11 on the same hardware. No problems
at all. But with the 9 series, a problem with every reboot.
Any advice?
PS. One thing I notice is that if I ever ensure correct permissions
of the .sujournal files, but setting them to the same values that
they already have, upon reboot I get an error message to the effect
"timestamp on journal doesn't match last mount time", and then there
is a fallback to a full fsck, most always followed by some cleared
inodes and file loss. Helpful hint or not, I don't know.
