/Deciding-when-to-use-Linux-file-system-barriers
It says, barriers can not work with device mapper (raid, lvm).
If it is true (?) then because of having all partitions in raid1 (md),
I need not worry about barriers. Whatever filesystem I picked out,
I could not use barriers...
Jarry
just
checkt man-page of mount, and it does not show btrfs
as supported filesystem...
Jarry
research I have found two candidates:
JFS (created by IBM)
XFS (created by SGI)
Now without trying to start flame-war, my question is:
which of them could be better for my need?
More stable, more reliable, more efficient, etc.
Or should I consider some different filesystem?
Jarry
know, I could have started it with:
nohup emerge -uv gcc
But I forgot to do it that way, and now I'm sitting, watching
messages scrolling in my shell. So is there any way to do
this nohup-trick on running process?

the first time, and since then exactly every 2 minutes.
I think it was the day when I updated to openssh-5.6-p1-r2.
So first of all, what does the message mean? And next,
how can I turn it off, or at least reduce its frequency?
