I''ve been playing with the fsstat provider lately. I''m curious why its gone undocumented and largely ignored (per google). I admit that I did experience some oddities with the data, so I''d also like to rule out whether or not it has problems which might have caused it to be left in quietly. benr.

Hi gurus, I like zpool iostat and I like system monitoring, so I setup a script within sma to let me get the zpool iostat figures through snmp. The problem is that as zpool iostat is only run once for each snmp query, it always reports a static set of figures, like so: root at exodus:snmp # zpool iostat -v capacity operations bandwidth pool used avail read

Recently, I''m benchmarking all kinds of stuff on my systems. And one question I can''t intelligently answer is what blocksize I should use in these tests. I assume there is something which monitors present disk activity, that I could run on my production servers, to give me some statistics of the block sizes that the users are actually performing on the production server.

Will the ability to import a destroyed ZFS pool and the fsstat command that''s part of the latest Solaris Express release (B38) make it into Solaris 10 Update-2 when it''s released in June/July??? Also has any decision been made yet what build Update-2 will be taken from to give an idea of what can be expected for ZFS??? This message posted...

Howdy, I wrote a pair of scripts to measure file and NFSv3 operations, and thought I would share them with the folks on the list. You can view the script output by pointing your browser at the following URLs: Per Process NFSv3 Client statistics (inspired by fsstat/nfsstat): http://daemons.net/~matty/code/nfsclientstats.pl.txt Per Process File Operations (inspired by fsstat): http://daemons.net/~matty/code/dfsstat.pl.txt If you think the scripts are useful, you can snag them from my website: http://daemons.net/~matty I plan to add NFSv4 support to n...

We''re running a Cyrus IMAP server on a T2000 under Solaris 10 with about 1 TB of mailboxes on ZFS filesystems. Recently, when under load, we''ve had incidents where IMAP operations became very slow. The general symptoms are that the number of imapd, pop3d, and lmtpd processes increases, the CPU load average increases, but the ZFS I/O bandwidth decreases. At the same time, ZFS

...problem we have is that new servers have performance problems. Even when have a small part of our total users (about 25%) directed to the new farm, performance is very poor, even useless. Looking for NFS problems, we have found a lot of differences in nfs operations. For example, this is the nfsstat of one of a new servers at this moment: myotis21:~# nfsstat Client rpc stats: calls retrans authrefrsh 414528349 885 37 Client nfs v3: null getattr setattr lookup access readlink 0 0% 95673837 23% 3961938 0% 89586364 21% 110097351 26% 2930961...

...(prstat, fstat, iostat, mpstat) are consumming some CPU. - zpool iostat -v tank 5 is frozen (It freezes when I issue a zpool clear rpool c4t0d7s0 in another session) - iostat -xn is not stuck but shows all zeroes since the very moment zpool iostat froze (which is quite strange if you look at fsstat ouput hereafter). NB: when I say all zeroes, I really mea nit, it''s not zero dot domething, its zero dot zero. - mpstat shows normal activity (almost nothing since this is a test machine, so only a few percent are used, but it still shows some activity and refreshes correctly) CPU minf...

..., wheter the problem is in linux or in solaris or in samba or elsewhere?? Using the nfs-shares directly from linux with cp seems to work, sometimes fast, sometimes slow. So it seems to be the combination samba and nfs. Perhaps statistics helps to understand, what happens. Output from /usr/sbin/nfsstat on linux-side: ...

Hi, I just wanted to relate the solution to a problem I was having to hopefully save someone else a day of frustration. I'm using rsync-2.5.5 on AIX 4.3, compiled with gcc 2.95.3. The file I was sync'ing was very large (>2GB). Despite being configured with --enable-largefiles (which #defines _LARGE_FILES properly for AIX), and despite the fact that the initial transfer of said file

...d on a read-only mount because it's only required for certain modifications at ENOSPC that can't be reserved ahead of time (e.g. btree blocks for an extent split during unwritten extent conversion at ENOSPC). The numbers above will be slightly more than 5%, because total blocks reported in fsstat doesn't include things like th space used by the journal, whereas the reserve pool sizing just works from raw sizes in the on-disk superblock. So total fs size is at least 24713 blocks. 5% of that is 1235.6 blocks. The difference in free blocks is 24653 - 23347 = 1306 blocks. It's right in...
