Building file server for multi-tera capacity

[Valerio Daelli]

Hi

we plan a FreeBSD server which can host
at least 20 Terabyte of data.
The system will be shipped with FreeBSD 7 or 8 and will be based
on a NexSAN SAS Beast.

We would like to know if anybody has tried FreeBSD with NexSAN products
and particularly if he has a suggestion about a solid HBA.
Also we would like to hear your opinion about ZFS with this  
configuration.


Greetings

Valerio Daelli

Port of perl 5.10

[Valerio Daelli]

Hi

is there anyone working on a port of perl5.10?
I can only see ports of 5.8 and 5.6.
I can make a port of 5.10, it seems to compile flawlessly on FreeBSD 7.
Have a good day

Bad performance of 7.0 nfs client with Solaris nfs server

[Valerio Daelli]

Hi list

we have a FreeBSD 7.0 NFS client (csup today, built world and kernel).
It mounts a Solaris 10 NFS share.
We have bad performance with 7.0 (3MB/s).
We have tried both UDP and TCP mounts, both sync and async.
This is our mount:

nest.xx.xx:/data/export/hosts/bsd7.xx.xx/ /mnt/nest.xx.xx nfs
noatime,async,-i,rw,-T,-3

Both our server (7.0 and Solaris 10) are Gigabit Ethernet, both are HP
Proliant DL360 i386 (NIC bge0):

---
FreeBSD 7.0:

[EMAIL PROTECTED] ~]$ uname -a
FreeBSD bsd7.xx.xx 7.0-RC2 FreeBSD 7.0-RC2 #1: Mon Feb 18 17:46:46 CET
2008 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/BSD7  i386

---
This is our performance with iozone:
command line:

iozone -+q 1 -i 0 -i 1 -n 2048 -g 2G -Raceb iozone.xls -f
/mnt/nest.xx.xx/iozone.bsd7/iozone.tmp

FreeBSD 7:

File stride size set to 17 * record size.
random
randombkwd  record  stride
  KB  reclen   write rewritereadrereadread

4096409628293364   699351   699807


As you can see, while with record length less than 1024KB the speed is
'fast', with record of 2048 or more (I've tried with record much
bigger) we get only
3 MB/s.
Is this a known issue? If you need more details please contact me, I
am willing to do more tests to risolve this problem.
Thanks

nfsv4: strange things happen

[Valerio Daelli]

Hi

we have a Solaris 10 NFS server and a FreebSD 7.0 NFS client.
We have a couple of NFSv4 mounted filesystem on the client.

nest.ifom-ieo-campus.it:/data/exports/obj/bsd7.ifom-ieo-campus.it/obj
/mnt/nest nfs rw,-r=16384,-w=16384,tcp,-4  2   0
nest.ifom-ieo-campus.it:/data/exports/jails/bsd7.ifom-ieo-campus.it/jails
/jails nfs rw,-r=16384,-w=16384,tcp,-4   2   0

We are having strange issues: for example
- we cannot execute binaries on the mounted filesystems
- if we umount one of the two filesystem from the client, the other filesystem
must be remounted, otherwise a process the is writing on it exit with
errors. For example
we have a iozone running on /mnt/nest and we umount /jails, the
iozoine exits with:

Can not open temp file: iozone.tmp
open: Unknown error: 10011
[EMAIL PROTECTED]:/mnt/nest/iozone/nfs4

Is anybody using nfsv4 between a Solaris 10 server and a FreebSD 7.0 client?
Are you having problems on it?

This is our FreeBSD version:
[EMAIL PROTECTED]:~ uname -a
FreeBSD bsd7.ifom-ieo-campus.it 7.0-RC1 FreeBSD 7.0-RC1 #0: Fri Jan 11

(everything si running fine on nfsv3).

Question about a patch

[Valerio Daelli]

Hi

I am about to send a patch about a port. I would like to move a file
of the port, located in the
'files/' directory. Basically the file now is called netdisco.sh.in
and I would like to call it
netdisco.in.
If I use a normal 'diff -ruN' command to generate the patch, after I
apply the patch
the new file is created but the old file (netdisco.sh.in) is still
there, with zero size.
I wonder if I should generate a shar archive for this port instead of a patch.
Sorry if this question is so simple.

We are not able to login via console nor via ssh.
Pheraps you suggest me to press Control-T on the console even if I am not
logged on. I did not try, sorry.

What you explained us sounds very interesting. But anyway we simply
solved by disabling background fsck on such a big partition. We had
panics and reboot
and we did not want to risk on a production host.

fsck of big disk

[Valerio Daelli]

Hi list

we have a freshly installed FreeBSD 6.2 machine with a gstriped external disk,
of 5.3Tb. The disk is composed of two slices of 2.6 Tb.
We are trying to have a (background) fsck of it but few hours later
since the start of the check
the host get unresponsive: it responds to ping but it doesn't let
login anyone, nor by ssh
nor by console.
In the meanwhile we are having a large rsync from another host.
Tonight during the fsck/rsync we had a reboot, without special
messages on the console.
We have 1Gb of RAM on this server.
Is 1Gb too small as memory to have a fsck and a rsync on a server with
5.3Gb as external disk?
Thanks for your precious help

Valerio Daelli

Please substitute the line starting with 'cp' with this one:

rsync -rlpgoD /backup/ $MOUNT/$DATE

(you must portinstall rsync as well)
since 'cp -rp' preserve modification times as well while 'rsync -rlpgoD'
preserve permission but not mtime.

[OT] Rotate logs for openbgpd

[Valerio Daelli]

Hi
we use openbgpd-4.0 from ports. We would like to rotate its logs
with newsyslog but if we send the daemon the HUP or USR1 signal
it does not close its old, already-rotated log file.
Does anyone by accident know the correct signal to get openbgpd close
its old log file?
Maybe we should use 'bgpctl reload'?

Monitoring tool for Compaq Smart Array 5300

[Valerio Daelli]

Hi
we would like to monitor the status of a Compaq Smart Array 5300
installed on a HP Proliant DL360.
Is there any tool for FreeBSD 6.2?
Thanks for the help

Fwd: top(1) STATE column

They're only documented in the source, as far as I know.  A quick grep
comes up with around 300 different unique waits and mutexes in the
kernel:

Error in man page of sendmsg?

[Valerio daelli]

Hi

working with InterMapper (a network tool) on FreeBSD 5.4 I got a

sendmsg -1 errno 22 Invalid argument

I looked in man sendmsg in the errors but I found no EINVAL in the errors.
So I looked at the kernel sources and I found

--

static int
sendit(td, s, mp, flags)
   register struct thread *td;
   int s;
   register struct msghdr *mp;
   int flags;
{
   struct mbuf *control;
   struct sockaddr *to;
   int error;

   if (mp->msg_name != NULL) {
   error = getsockaddr(&to, mp->msg_name, mp->msg_namelen);
   if (error) {
   to = NULL;
   goto bad;
   }
   mp->msg_name = to;
   } else {
   to = NULL;
   }

   if (mp->msg_control) {
   if (mp->msg_controllen < sizeof(struct cmsghdr)
#ifdef COMPAT_OLDSOCK
   && mp->msg_flags != MSG_COMPAT
#endif
   ) {
   error = EINVAL;

--

that error is set to EINVAL so the man page should report EINVAL as possible
error in this funcion.

Re: changing kern.ngroups

[Valerio daelli]

Cool. Any suggestion on what to do if I do want to change it?


We managed to get 64 groups changing these files

/usr/include/sys/syslimits.h
/usr/src/sys/sys/syslimits.h

NGROUPS_MAX from 16 to 64, then recompiling world.
We use NFS and we never had problems (more than one year running).
But I heard you may get some trouble with some hardcoded limits.

Question on NFS performance

[Valerio daelli]

Hi all
we have a FreeBSD 5.4 exporting some NFS filesystem to a cluster of gentoo boxes
(kernel 2.6.12).
Our exported storage disk is an Apple XRaid.
We have Gigabit Ethernet both on the client and the server.
We would like to improve our read performance.
This is our performance:

about 10Mb reading a file of 1Gb with dd

and iozone confirms this result.
We already use the normal optimization flags (we use rpc.lockd and
rpc.statd, on the client we have
read size 65536 and a read ahead of 4 blocks, the async options).
Is our performance the best we can get? Can we improve it?
Thanks for your help

Hang in 5.3, related to syslog-ng

[Valerio daelli]

Hi all
we have a server with 5.3 (latest patches) with twelve jails.
One of these jails is a mail server (mail-jail), serving about 300 users,
writing a lot of logs to /var/log/maillog.
On the same server I installed a jail with syslog-ng (syslog-jail).
syslog-ng was configured to listen on the network and write to
a named pipe.
On the same jail I created a script to read from that named pipe
and insert the result to mysql, but I didn't start this script.
I was about to start this system of logging, so I modified
/etc/syslog.conf in the mail-jail inserting a line like this:


mail.* @logger_with_syslog-ng.my.domain

then I restarted syslogd on the mail-jail sending a HUP signal.
Suddendly the system stopped responding to anything
(from ping to console, everything stopped).
I rebooted the server turning off the power and deleted that line in
syslog.conf.
Everything worked.
Could it be some issue related to a named pipe?
Or pheraps to syslogd? Or syslog-ng?
I tried recreating the situation on a test server with 5.4 but
everything worked.
Sorry if I don't have details but this is a very critical server for us
and I can't experiment.
Thanks

Number of routing tables

[Valerio daelli]

Hello
I would like to know if exists a sysctl to get the number of
routing tables in the kernel.
I don't want the list of the routing tables, I just want the number.
The command 'netstat -rn|wc -l' could be a good candidate,
but since I want to implement this command on a very busy router,
I don't want it to go 100% CPU just to get a simple count.
If it doesn't exist I will create something based on netstat's source.
Thanks a million (routes)

We have a configuration with 64 groups and it is pretty stable.
We modified the sources:

/usr/include/sys/syslimits.h
/usr/src/sys/sys/syslimits.h

and put the NGROUPS_MAX to 64.
Then we rebuilt everything and now it just works.

NFS over TCP on 5.4: client stucks

[Valerio daelli]

Hello everybody
I am trying to mount via NFS a directory exported from FreeBSD 5.4 on a
FreeBSD 5.4.
The server has these settings:

nfs_server_enable="YES"  # This host is an NFS server (or NO).
nfs_server_flags="-u -t -n 8"   # Flags to nfsd (if enabled).
nfs_reserved_port_only="YES" # Provide NFS only on secure port (or NO).
nfs_bufpackets="8"   # bufspace (in packets) for client
mountd_enable="YES"  # Run mountd (or NO).
rpcbind_enable="YES" # Run the portmapper service (YES/NO).
rpcbind_program="/usr/sbin/rpcbind" # path to rpcbind, if you want a
different one.
rpc_lockd_enable="YES"   # Run NFS rpc.lockd needed for
client/server.
rpc_statd_enable="YES"

and the client has these:

nfs_client_enable="YES"
nfs_access_cache="30"
nfs_bufpackets="8"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
rpcbind_enable="YES"

The client can mount the server via UDP, but not via TCP, it just stucks.
This is an extract from a tcpdump on the server

NFS export problem

[Valerio daelli]

Hello
I am trying to export two directories via NFS.
The two directories are on the same filesystem.
This is our /etc/exports file:

/raid/lower/data -maproot=root -network 10.210.0.0  -mask
255.255.0.0 
/raid/lower/home -maproot=nobody -network 10.210.0.0 -mask
255.255.0.0 
/raid/upper/db -maproot=root -network 10.210.0.0  -mask
255.255.0.0 
/raid/upper/scratch -maproot=root -network 10.210.0.0 -mask
255.255.0.0 

but we keep getting this strange errors in /var/log/messages:

Sep 29 17:38:46 biopresto mountd[411]: can't change attributes for
/raid/lower/home
Sep 29 17:38:46 biopresto mountd[411]: bad exports list line
/raid/lower/home -maproot

/raid/upper/scratch
Sep 29 17:38:46 biopresto mountd[411]: bad exports list line
/raid/upper/scratch -maproot

We heard that there could be some problems sharing two directories on the
same
filesystem.
Is this true?

Volume managers

[Valerio daelli]

Hello
we have an Apple XRAID disk and we would like to use it as a single disk,
joining its two disks of 2.5T each in order to get a single volume of 5T.
We are experiencing problems with vinum, we keep getting kernel panic
and we heard the vinum code is not very stable with 5.4.
Is there any other stable volume manager for freebsd we could try?
Thanks a lot

bsdlabel and c partition

[Valerio daelli]

Hi
I have partitioned a disk using bsdlabel and I have used
the c partition for the entire disk. According to the manual
this mean I have used the disk in dedicated mode.
Is there any danger in it?
Is it preferable to use another partition?

Grub not working

[Valerio daelli]

Hello 
I am trying to install grub as a boot loader on my disk.
I installed it from ports.
When I try to install it on the MBR I get the error

 Running "install /boot/grub/stage1 (hd0) /boot/grub/stage2 p /boot/grub/menu.l
st "... failed

Error 29: Disk write error

I tried to install it with 'grub-install '(hd0)'' and with grub ->
root (hd0,a) -> setup (hd0).
I tried deinstalling the port and installing from sources (version 0.97).
I don't think the problem is with menu.lst since I am using it with
linux (identical file)
and it works.
Anyone a guess?

fdisk problem

[Valerio daelli]

Hello everybody
we have a 2235Gb disk which we want to partition.
If we use sysinstall->Configure->Fdisk and try to build a unique slice
we get a message like

'Wrote FDISK partition information out successfully (100%)'

but if we go back to fdisk it shows a freebsd slice of 187Gb
plus an unused slice of 2048Gb.
If we delete it and recreate a new slice, the problem persists.
Is there any tutorial about using fdisk without using sysinstall?

Jails on NFS: locks on file

[Valerio Daelli]

Hi all,
we are using FreeBSD 5.4 with some jails.
One of this jail is on a NFS directory - I mean: the whole filesystem of 
this jail is on a remote directory, exported by a FreeBSD 5.4 server with 
NFS, and the 'host' system (the one that started and stopped the jail) 
mounts it via NFS. In this jail we can't perform a 'flock' operation, even 
if the NFS server has rpc.lockd and rpc.statd. We built a little executable 
in C like this (let's call it myflock):


___
#include 
#include 
#include 

int main() {
 int lockfd;
 char* tempfile="tempfile";

 lockfd=open(tempfile,O_CREAT);
 if (flock(lockfd, LOCK_SH|LOCK_NB)==-1) {
   printf("ERROR shared lock:  %d",errno);
 }
 if (flock(lockfd, LOCK_EX|LOCK_NB)==-1) {
   printf("ERROR exclusive lock:  %d",errno);
 }
  close(lockfd);
}
___

We executed on a local directory and it gets the flock.
We executed on the mounted NFS partition (with rpc.lockd and rpc.statd) and 
it works.
We executed in the jail-NFS and it fails! Errno 45 (from 
'/usr/include/errno.h': #define EOPNOTSUPP  45  /* Operation 
not supported */). The directory where we launch myflock is the same as the 
previous command (no permission problems).
We executed in a jail contained in a md mounted on a NFS directory and it 
works.
Could it be a rpcbind issue (the jail can't get the flock since it can't 
rpc-contact the NFS server)?

Thanks a lot

Re: vipw: could not lock the passwd file: : Operation not supported

[Valerio Daelli]

Yes, I am root. The problem is that some tools like vipw and pam utilities 
want
to get a flock on some files, like /etc/passwd. If they can't (because of 
plain NFS) they complain.

I've been suggested to try with rpc.lockd.
Thanks for your help!

Valerio Daelli


It sounds like your not logged in as root, I'm sure you are but I have
never played with jails. Have you tried the adduser or pw commands?,
vipw is not the best tool for adding users because you can fsck your
system if your not careful.

vipw: could not lock the passwd file: : Operation not supported

Hi all,
we have FreeBSD 5.4 jail which is mounted via NFS from a host machine.
The filesystem containing the jail is mounted from a remote machine.
Everything is fine, except when I try to add a user in the jail I get a:

I solved the problem in pwd_mkdb using the -i switch.
But I can't find any similar options in vipw.
Has anyone an idea about this?

FreeBSD on AlphaServer DS25

Hello
we are trying to install FreeBSD 5.4 (Alpha Version) on a AlphaServer DS25.
It fails when we start to boot from the CD.
This machine doesn't have any floppy so we cannot try the floppy install.

Statically linked bash

Hello
we are trying to compile a statically linked bash from ports.
I edited the Makefile in /usr/ports/shells/bash with '--enable-static-link' 
in CONFIGURE_ARGS.

But it didn't work (it compiled a dynamically linked one).
So I entered in work/bash-3.0 and configured by and with

./configure ...DEFAULT_ARGS...  --enable-static-link

But it didn't work.
So I edited every Makefile in these directories, to include in every gcc 
argument -static.

But It didn't work.
That's the last compile operation (notice the -static)

gcc -L./builtins -L./lib/readline -L./lib/readline -L./lib/glob

Linux Perl Program not working

[Valerio Daelli]

Hello everybody
we are trying to use a linux perl program called Mascot on FreeBSD. It is 
statistical-bioinformatic software.
We use this program on Linux RedHat 7.3 (glibc 2.3.2), perl 5.8.6.
We copied the program and the libraries.
We tried installing the ports linux_base (glibc 2.1.3), linux_base-rh-9 
(2.3.2).
What actually happens is this:
1) If we use freebsd-perl 5.8.6 (we tried the 'plain' and the ithreads one) 
when we launch this application it fails with a Bus error - core dump.
We did a 'strace' on it and it fails after loading some libraries (I report 
it at the end). This perl program goes into a 'use msparser;', then the 
msparser.pm file calls a msparser.so file which is a Gnu/Linux shared 
object. We could't recompile this library since we don't have source code. 
We just copied it from Linux.

/msparser.so:ELF 32-bit LSB shared object, Intel 80386, 
version 1 (GNU/Linux), not stripped

2) If we use an rpm-installed Active Perl 5.8.6 designed for Linux Red Hat, 
the program fails with:

Can't load '../bin/auto/msparser/msparser.so' for module msparser: 
../bin/auto/msparser/msparser.so: ELF file OS ABI invalid at 
/usr/local/ActivePerl-5.8/lib/5.8.6/i686-linux-thread-multi/DynaLoader.pm 
line 230.

Have anyone any idea what happened?
Thanks
