Re: ZFS hangs systems during copy

What kind of system is that? How much memory is installed?
I''m able to hang an Ultra 60 with 256 MByte of main memory,
simply by writing big files to a ZFS filesystem. The problem
happens with both Solaris 10 6/2006 and Solaris Express snv_48.
In my case there seems to be a problem with ZFS'' ARC cache,
which is not returning memory to the kernel, when free memory
gets low. Instead, ZFS'' ARC cache data structures keeps growing
until the machine is running out of kernel memory. At this point
the machine hangs, lots of...

zfs/fstyp slows down recognizing pcfs formatted floppies
I''ve noticed that fstyp on a floppy media formatted with "pcfs" now needs somewhere between
30 - 100 seconds to find out that the floppy media is formatted with "pcfs".
E.g. on sparc snv_48, I currently observe this:
% time fstyp /vol/dev/rdiskette0/nomedia
pcfs
0.01u 0.10s 1:38.84 0.1%
zfs''s /usr/lib/fs/zfs/fstyp.so.1 seems to add about 40 seconds to that time, because it
reads 1 mbyte from the floppy media (~ 2/3 of a 1.44MB floppy), only to find out that the
floppy media...

Some performance questions with ZFS/NFS/DNLC at snv_48
Hello.
We''re currently using a Sun Blade1000 (2x750MHz, 1G ram, 2x160MB/s mpt
scsi buses, skge GigE network) as a NFS backend with ZFS for
distribution of free software like Debian (cdimage.debian.org,
ftp.se.debian.org) and have run into some performance issues.
We are running SX snv_48 and have run with a raidz2 with 7x300G for a
while now, just added another 7x300G raidz2 today but I''ll stick to old
information so far. Tried Sol10u2 before, but nfs writes killed every
bit of performance, snv_48 works much better in that regard.
Working data set is about 1.2TB over ~550...

Performance problem of ZFS ( Sol 10U2 )
Hi,
I deployed ZFS on our mailserver recently, hoping for eternal peace after running on UFS and moving files witch each TB added.
It is mailserver - it''s mdirs are on ZFS pool:
