Un(un)mountable file system

After hitting this bug (yes, again and again) I had to unmount the broken file system and run fsck (twice). But then I apparently hit anoter bug (or a feature?) - I could not mount the file system back.

xeon# mount /dev/dsk/c2d0s3 /export/docs
mount: /dev/dsk/c2d0s3 is already mounted or /export/docs is busy

Neither pwdx not lsof showed any processes using /export/docs. The solution was to recreate the directory:

xeon# rm -rf docs
xeon# mkdir docs
xeon# mount /dev/dsk/c2d0s3 /export/docs (after a loooong pause)
xeon# mount | fgrep docs
/export/docs on /dev/dsk/c2d0s3 read/write/setuid/devices/intr/largefiles/logging/xattr/onerror=panic/dev=1980043 on Tue Jul  1 01:07:08 2008

Unkillable process

Snv_92 has been entertaining me since I upgraded from quite stable snv_88. I’m hitting a bug after a bug. (See here).

This is the latest - unkillable process, which can’t be killed with kill -9 or zone reboot. Reboot just hangs. Truss ends up with:

xeon# kill -9 22131
xeon# ps -ef | fgrep 22131
root 22728 5471 0 00:49:27 pts/5 0:00 fgrep 22131
alekz 22131 1 0 20:48:30 zoneconsole 0:03 /opt/sfw/lib/firefox/firefox-bin -P Sun –no-remote
xeon# truss -p 22131
^Ctruss: unanticipated system error: 22131

dtrace shows nothing. The only workaround is to reboot the entire system.

Solaris and ATA and SCSI errors

After upgrading from snv_88 to snv_92 (Solaris 11 or Nevada b92) my home server started spewing  the following errors:

SqueezeCenter and Compress::Zlib

After upgrading to Nevada b92 SqueezeCenter refused to start with the following error:

The following modules failed to load: Compress::Zlib

# perl -MCPAN -e shell
cpan> install Compress::Zlib
. . .
Module [Compress::Zlib] failed to load: is only available with the XS version
. . .

But the actual problem is Scalar::Util. To solve the problem reinstall Scalar::Util and then Compress::Zlib. Use force install if CPAN says that the latest version is already installed:

# perl -MCPAN -e shell
. . .
cpan[1]> install Scalar::Util
CPAN: Storable loaded ok (v2.12)
Going to read /var/tmp/cpan/Metadata
Database was generated on Tue, 24 Jun 2008 10:02:57 GMT
Scalar::Util is up to date (1.19).
cpan[2]> force install Scalar::Util
. . .
cpan[3]> force install Compress::Zlib
. . .

SqueezeCenter 7.1 under Solaris

The idea was to use “bare” SqueezeCenter without bundled CPAN (the CPAN directory was moved away) modules, Solaris 11 (or Nevada build 88) and supplied with Solaris PERL and MySQL.

Then if you start slimserver.pl the errors will let you know which CPAN modules to install. For example:

The following modules failed to load: version JSON::XS YAML::Syck GD
. . .
Can’t locate JSON::XS.pm in @INC (@INC contains: squeezecenter-7.1-19407-noCPAN/CPAN/arch/5.8/i86pc-solaris-64int

To install a module run the following:

# perl -MCPAN -e shell
cpan[1]> install JSON::XS

The only exception is Encode/Detect/Detector.pm or Encode::Detect::Detector. It’s has not being touched by the developer for many years and is not recommended for use. The module can be compiled with c++ or g++ (instead of used by default cc or gcc), but with a lot of pain and manual intervention. The easiest way is to get rid of it completely:

  • Remove Encode::Detect::Detector from modules.conf (in the root directory of SqueezeCenter)
  • Remove or comment the following line in Slim/Utils/Unicode.pm:
    use Encode::Detect::Detector;

Solaris snv_88 and wine 0.9.61

For the first time I did not have to do anything special to compile wine. Just configure and gmake. The rest is pretty the same: Picasa runs at 100% CPU load, Firefox 3b5 crashes every 5 minutes ;-)

What process is using this port?

If lsof is installed in your system:

xeon# lsof 2>/dev/null | fgrep :telnet
telnet 18409 alekz 4u IPv4 0xffffff0e3b19c740 0t0 TCP xeon:52431->10.0.0.1:telnet (UknownState_-2094513781)

xeon# lsof 2>/dev/null | fgrep :8080
firefox-b 699 alekz 52u IPv4 0xffffff02db1e0780 0t110637 TCP xeon:51567->dmz:8080 (UknownState_-2094513781)
firefox-b 699 alekz 67u IPv4 0xffffff0e3b0e06c0 0t127870 TCP xeon:47231->dmz:8080 (UknownState_-2094513781)
squid 2778 nobody 8u IPv4 0xffffff01dc8ce080 0t0 TCP *:8080 (UknownState_-359969560)
squid 2778 nobody 22u IPv4 0xffffff01dc6d36c0 0t110637 TCP dmz:8080->xeon:51567 (UknownState_-2094513781)
squid 2778 nobody 41u IPv4 0xffffff01dc8c26c0 0t127870 TCP dmz:8080->xeon:47231 (UknownState_-2094513781)

If lsof is not installed:

  • Run pfiles /proc/* | less
  • Search for port:
    • Press </>
    • Type port: 23
    • Press <Enter>

The result may look like:

18409: telnet 10.0.0.1
. . .
4: S_IFSOCK mode:0666 dev:318,0 ino:42212 uid:0 gid:0 size:0

peername: AF_INET 10.0.0.1 port: 23
