[Bug 10950] New: rsync hangs when specifying a backup directory
https://bugzilla.samba.org/show_bug.cgi?id=10950
Bug ID: 10950
Summary: rsync hangs when specifying a backup directory
Product: rsync
Version: 3.1.0
Hardware: x64
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: core
Assignee: wayned at samba.org
Reporter: bugzilla.samba at familie-kinder.de
QA Contact: rsync-qa at samba.org
rsync hangs after working a few minutes without any error messages.
Since I have upgraded from Ubuntu 12.04.5 to Ubuntu 14.04 rsync comes in
version 3.1.0. And since the upgrade rsync hangs if I specify a backup
directory by the parameters "--backup --backup-dir=...".
Without the both backup parameters rsync works fine as before the upgrade!
So I tried the argument "--block-size" as described in
https://bugzilla.samba.org/show_bug.cgi?id=10518#c8 although I think it is
another issue there because I don't have large vm files.
But if I specify 10 MB I get the error: "rsync: --block-size=10485760 is
too
large (max: 131072)". And with 131072 rsync hangs too.
Now I tried the arguments "--protocol=30" and
"--protocol=29", but rsync hangs
too - also in combination: "--block-size=131072 --protocol=29".
Also the option "--no-inc-recursive" isn't helpfull (as described
in
https://bugzilla.samba.org/show_bug.cgi?id=8804#c0) and rsync hangs with it
too.
The parameters to rsync are:
/usr/bin/rsync --recursive --links --hard-links --perms --times --group --owner
--devices --specials --backup
--backup-dir=/backup/rsync-backup/14.04/incremental/2014-11-20_08-23-41
--delete --numeric-ids
--exclude-from=/usr/local/bin/rsync-backup/rsync-backup.13.usbhdd_toshiba_2t.usbhdd_trekstor_500g.conf.d/rsync-backup.exclude.list
--files-from=/usr/local/bin/rsync-backup/rsync-backup.13.usbhdd_toshiba_2t.usbhdd_trekstor_500g.conf.d/rsync-backup.include.list
