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.

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
. . .

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

SO_OOBINLINE,SO_SNDBUF(49152),SO_RCVBUF(49640)

peername: AF_INET 10.0.0.1 port: 23
