NFS/ZFS performance problems - txg_wait_open() deadlocks?
Hi.
System is snv_56 sun4u sparc SUNW,Sun-Fire-V440, zil_disable=1
We see many operation on nfs clients to that server really slow (like 90 seconds for unlink()).
It''s not a problem with network, there''s also plenty oc CPU available.
Storage isn''t saturated either.
First strange thing - normally on that server nfsd has about 1500-2500 number of threads.

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:

ZFS panic in space_map.c line 125
One of our Solaris 10 update 3 servers paniced today with the following error:

ZFS panic when trying to import pool
I have a raid-z zfs filesystem with 3 disks. The disk was starting have read and write errors.
The disks was so bad that I started to have trans_err. The server lock up and the server was reset. Then now when trying to import the pool the system panic.
I installed the last Recommend on my Solaris U3 and also install the last Kernel patch (120011-14).
But still when trying to do zpool import

ZFS checksum error detection
Hi all.
A quick question about the checksum error detection routines in ZFS.
Surely ZFS can decide about checksum errors in a redundant environment but
what about an non-redundant one? We connected a single RAID5 array to a
v440 as a NFS server and while doing backups and the like we see the
"zpool status -v" checksum error counters increment once in a while.
Nevertheless the

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 send/receive : panic and reboot

I kept on trying to migrate my pool with children (see previous threads) and had the (bad) idea to try the -d option on the receive part.
The system reboots immediately.

slow sync on zfs
Hello zfs-discuss,
Relatively low traffic to the pool but sync takes too long to complete
and other operations are also not that fast.
Disks are on 3510 array. zil_disable=1.

real 1:21.569
user 0.001

During sync zpool iostat and vmstat look like:

Probe ID changes
OK, I''ve been fritzing around with something I noticed last night,
thinking that I understood what was going on, but now it''s getting
confusing again.
A system that has been running for a couple of months had a hole in the
probe ID list near the end in the middle of the fbt probes. And then a
couple of syscall probes were stuck in the hole. It looked like this:

Qs. on fbt::copystr: probe

I have questions about something I observed just now:
1) on AMD64, S10u1:

dtrace: invalid probe specifier fbt::copystr:entry{printf ("%p\n",

Limiting dtrace depth
If I use a simple dtrace script such as this:
fbt::somefunc:entry{self->trace=1;}
fbt::somefunc:return{self->trace=0;}
fbt:::entry{}
fbt:::return{printf("%lx", arg1);}
then it will descend to whatever depth is necessary
If I want to limit it to say 3 functions deep, how can I do that?
The quick answer I want to use is to do "self->depth++" on each entry
and then

How do I look up syscall name
I''m using a fbt probe where I get a system call id as an argument, how do I look up the name of it? At the moment I''m post-processing the output using /etc/name/to_sysnum but that doesn''t feel right :)
cheers,

Error trying to count return points in functions.
Whilst trying out some D to get an insight into what is the most
common reason for a given function to return, I have bumped
into an error I don''t understand.
The first take on what I was trying to do was:
# dtrace -n ''fbt:ip:ip_input:return{@home[arg0] = count();}''
and all was well. The next step was:

FBT Provider
Is there a list anywhere of the DTrace FBT provider calls for each version of Solaris since the Nevada build that hosed the DTrace Toolkit. I have no issue with rewriting what I need, but I am hoping to stave off having to look at all the source code to find everything. I know there is a new provider under development, but I need to be able to program DTrace routines for all the updates in
