Subject: rsync in some cases fails to detect disk full condition Package: rsync Version: 3.0.3-2 Severity: important
The rsync client will get stuck in some scenarios if a disk full condition occurs at the server side. In a rsycnc-based backup system (network connection via ssh), I am running into a nasty problem. Actually, it is a combination of 2 problems: 1) If on the client side a filesystem is mounted after rsync has started, it will include this filesystem, even if called with "--one-file-system" (which is sad, but probably would be very hard to avoid due to the design of rsync) 2) If in this situation the server runs out of disk space (which is likely to happen if the accidentally included file system is large), the server notices the error but obviously just exits without notifying the client which doesn't notice the error and hangs until killed. The server writes something like this to the syslog: rsyncd[8493]: receiving file list rsync: write failed on \"/some/file\" (in backup): No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(298) [receiver=3.0.3] connection unexpectedly closed (550 bytes received so far) [generator] rsync error: error in rsync protocol data stream (code 12) at io.c(635) [generator=3.0.3] while on the client side there is no indication that something went wrong. In general, the handling of "disk full" conditions on the server side seems to vary (I guess, depending on what exactly fails) and is not always really gracefull (often the log gets flooded with error messages for every single failed operation), but at least eventually all processes will terminate and the client will notice that something went wrong. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-1-amd64 (SMP w/4 CPU cores) Locale: LANG=C, LC_CTYPE=en_US.ISO-8859-1 (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/bash Versions of packages rsync depends on: ii base-files 4.0.5 Debian base system miscellaneous f ii libacl1 2.2.47-2 Access control list shared library ii libc6 2.7-15 GNU C Library: Shared libraries ii libpopt0 1.14-4 lib for parsing cmdline parameters ii lsb-base 3.2-20 Linux Standard Base 3.2 init scrip rsync recommends no packages.
