zpool export consumes whole CPU and takes more than 30 minutes to complete
Hi.
T2000 1.2GHz 8-core, 32GB RAM, S10U3, zil_disable=1.
Command ''zpool export f3-2'' is hung for 30 minutes now and still is going.
Nothing else is running on the server. I can see one CPU being 100% in SYS like:
bash-3.00# mpstat 1

Direct I/O ability with zfs?
We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs?

ZFS space map causing slow performance
Hello,
I have several ~12TB storage servers using Solaris with ZFS. Two of them have recently developed performance issues where the majority of time in an spa_sync() will be spent in the space_map_*() functions. During this time, "zpool iostat" will show 0 writes to disk, while it does hundreds or thousands of small (~3KB) reads each second, presumably reading space map data from

ZFS pool fragmentation
I have a huge problem with ZFS pool fragmentation.
I started investigating problem about 2 weeks ago http://www.opensolaris.org/jive/thread.jspa?threadID=34423&tstart=0
I found workaround for now - changing recordsize - but I want better solution.
The best solution would be a defragmentator tool, but I can see that it is not easy.

pid-provider sees ld.so.1 only
I''m trying to do some userspace tracing on a server-process with the pid provider.
My problem is, that the only probes the pid-provider lists for the server-process (to which I attach dtrace with "-p nnnn") are coming from "ld.so.1".
There''s not a single one from my modules.

Optimal File Permissions for Shared Access Between Windows and Linux
Hi Rowland,
Thank you for your feedback. I apologize for not including the global
section in my previous message. Here it is:
[global]

?? workgroup = WORKGROUP
As you can see, there isn?t much in the global section.
To answer your question about the permissions on |/mnt/shared|, here are

mdraid doesn't allow creation: device or resource busy
Dear fellow CentOS users,
I have never experienced this problem with hard disk management before
and
cannot explain it to myself on any rational basis.
The setup:
I have a workstation for testing, running latest CentOS 7.3 AMD64. I am
evaluating oVirt and a storage-ha as part of my bachelors thesis.
I have already been running a RAID1 (mdraid, lvm2) for the system and
some oVirt 4.1 testing.

zpool kernel panics.
Hi Folks,
I''ve got a 3.9 Tb zpool, and it is casing kernel panics on my Solaris
10 280r (SPARC) server.
The message I get on panic is this:
panic[cpu1]/thread=2a100a95cc0: zfs: freeing free segment
(offset=423713792 size=1024)
This seems to come about when the zpool is being used or being
scrubbed - about twice a day at the moment. After the reboot, the
scrub seems to have

Possible ZFS Bug - Causes OpenSolaris Crash
I?d like to report the ZFS related crash/bug described below. How do I go about reporting the crash and what additional information is needed?
I?m using my own very simple test app that creates numerous directories and files of randomly generated data. I have run the test app on two machines, both 64 bit.
OpenSolaris crashes a few minutes after starting my test app. The crash has occurred on

gzip compression throttles system?
I just had a quick play with gzip compression on a filesystem and the
result was the machine grinding to a halt while copying some large
(.wav) files to it from another filesystem in the same pool.
The system became very unresponsive, taking several seconds to echo
keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty
of grunt for this.
Comments?
