Package: lsof Version: 4.81.dfsg.1-1 Severity: normal After the upgrade of libcurl, my read-only system (using a flash card instead of a disk) cannot be remounted read-only anymore.
wall:/# mount -o remount,ro / mount: / is busy lsof -n | grep curl shows no matches, so it does not seem like some process is still holding the library files open from before they were replaced. All open files are either pipes or rest on separate tmpfs. lsof does not show why the root filesystem cannot be remounted: wall:/# lsof -n | egrep '[0-9]w|DEL' udevd 646 root 7w FIFO 0,6 1249 pipe rsyslogd 1885 root 1w REG 0,20 319941 12495655 /var/log/auth.log rsyslogd 1885 root 2w REG 0,20 52162 14130106 /var/log/syslog rsyslogd 1885 root 3w REG 0,20 4233406 12495568 /var/log/daemon.log rsyslogd 1885 root 4w REG 0,20 869126 12495649 /var/log/kern.log rsyslogd 1885 root 5w REG 0,20 0 3645 /var/log/lpr.log rsyslogd 1885 root 6w REG 0,20 535697 12495552 /var/log/mail.log rsyslogd 1885 root 7w REG 0,20 0 3647 /var/log/user.log rsyslogd 1885 root 8w REG 0,20 535697 12495548 /var/log/mail.info rsyslogd 1885 root 9w REG 0,20 0 3649 /var/log/mail.warn rsyslogd 1885 root 10w REG 0,20 0 3650 /var/log/mail.err rsyslogd 1885 root 11w REG 0,20 0 3652 /var/log/news/news.crit rsyslogd 1885 root 12w REG 0,20 0 3653 /var/log/news/news.err rsyslogd 1885 root 13w REG 0,20 0 3654 /var/log/news/news.notice rsyslogd 1885 root 14w REG 0,20 1680 12495658 /var/log/debug rsyslogd 1885 root 15w REG 0,20 958547 12495743 /var/log/messages master 2143 root 104w FIFO 0,6 4250 pipe master 2143 root 106w FIFO 0,6 4251 pipe xinetd 2487 root 4w FIFO 0,6 4559 pipe cron 2616 root 1w CHR 1,3 219 /dev/null cron 2616 root 2w CHR 1,3 219 /dev/null watchdog 2632 root 1w CHR 10,130 3617 /dev/watchdog fail2ban- 3011 root 6w REG 0,20 2894 12495201 /var/log/fail2ban.log sshd 5760 root DEL REG 0,8 14153140 /dev/zero sshd 5760 root DEL REG 0,8 14153128 /dev/zero sshd 5760 root 4w unix 0xd96bf0a0 14153141 socket sshd 5762 madduck DEL REG 0,8 14153140 /dev/zero sshd 5762 madduck DEL REG 0,8 14153128 /dev/zero sshd 5762 madduck 7w FIFO 0,6 14153144 pipe puppetd 9811 root 1w CHR 1,3 219 /dev/null puppetd 9811 root 2w CHR 1,3 219 /dev/null puppetd 9811 root 4w FIFO 0,6 13319 pipe lsof 10563 root 1w FIFO 0,6 14159611 pipe lsof 10563 root 5w FIFO 0,6 14159617 pipe lsof 10565 root 7w FIFO 0,6 14159618 pipe dhclient3 10732 root 4w REG 0,23 2838 567454 /var/lib/dhcp3/dhclient.leases aiccu 10933 root 1w CHR 1,3 219 /dev/null aiccu 10933 root 2w CHR 1,3 219 /dev/null dhcpd3 14054 root 8w REG 0,23 1152 9532099 /var/lib/dhcp3/dhcpd.leases screen 23726 root 1w CHR 1,3 219 /dev/null screen 23726 root 2w CHR 1,3 219 /dev/null radvd 25197 radvd 6w FIFO 0,6 2709576 pipe dhclient3 25677 root 4w REG 0,23 8987 2771 /var/lib/dhcp3/dhclient.wan.leases qmgr 25713 postfix 4w FIFO 0,6 4251 pipe openvpn 25754 nobody 4w REG 0,15 308 13091445 /var/run/openvpn.madduck.status openvpn 25760 nobody 4w REG 0,15 267 13091458 /var/run/openvpn.reloc.status tlsmgr 25769 postfix 4w FIFO 0,6 4251 pipe pickup 28994 postfix 4w FIFO 0,6 4251 pipe wall:/# df -T /dev /var/lib/dhcp3 /var/log /var/run Filesystem Type 1K-blocks Used Available Use% Mounted on udev tmpfs 10240 24 10216 1% /dev dhcp3-lib tmpfs 64 24 40 38% /var/lib/dhcp3 varlog tmpfs 32768 17308 15460 53% /var/log varrun tmpfs 258268 88 258180 1% /var/run -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.31-rc3-amd64 (SMP w/1 CPU core) Locale: LANG=en_GB, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages lsof depends on: ii libc6 2.9-25 GNU C Library: Shared libraries lsof recommends no packages. lsof suggests no packages. -- no debconf information -- .''`. martin f. krafft <madd...@d.o> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems
