Hello!
I think I've found a bug in some (older) versions of rsync.
The problem does not seem to have been reported at bugzilla.
And of the 9 bugs found there by searching on "--delete-after"
all have got the name wayned@samba.org attached.
I ask you therefore to check if this problem is found in the newest
version of rsync as well!
I've read the warnings at rsync.samba.org concering when and how to
report bugs/postings to the rsync list.
(It would have been a nice feature to be able to search the complete
archive at http://lists.samba.org/archive/rsync/ for "--delete-after")
The problem is in short that rsync used with the option --delete-after
does NOT delete older files rsynced, but --delete does.
I choosed initially --delete-after to keep copies until all new files
where copied so there should always be an online copy of the file.
The versions I have used is, from [fra (no.)]
hox /# rsync --version
rsync version 2.5.5 protocol version 26
- and to [til (no.)]:
hox /# ssh anvil rsync --version
rsync version 2.6.2 protocol version 28
The newer command is on the machine hox:
while read fra til;
rsync -a -H -p -x --delete --exclude quota.user --exclude quota.group \
--rsync-path=/rsync $fra/ anvil:$til
done < /rsynke
The old was the same, just with --delete-after and not --delete
The datafile /rsynke:
i# cat /rsynke
/mn/hox/geofysikk /mn/anvil/geofysikk
/mn/hox/u4 /mn/anvil/adm-u1
/mn/hox/u6 /mn/anvil/student-u2
/mn/hox/u1 /mn/anvil/ozon-u1
/mn/hox/u8 /mn/anvil/ozon-u2
/mn/hox/u11 /mn/anvil/dynmet-u3
/mn/hox/u10 /mn/anvil/ozon-u4
/mn/hox/student-u1 /mn/anvil/student-u1
/mn/hox/u5 /mn/anvil/hydro-u1
/mn/hox/u9 /mn/anvil/ozon-u3
/mn/hox/u7 /mn/anvil/dynmet-u2
/mn/hox/u2 /mn/anvil/osean-u1
/mn/hox/u3 /mn/anvil/dynmet-u1
/mn/hox/u12 /mn/anvil/slettes-u1
Here is a before and after status of the most troublesome disk; the
first the from-disk and the last two the to-disk; of these the first by
use of --delete-after and the last by use of --delete:
hox /# df -h /mn/hox/u7
Filesystem Size Used Available Capacity Mounted
enhalvtil#dynmet2 29G 23G 6003M 80% /mn/hox/u7
hox /# ssh anvil df -h /mn/anvil/dynmet-u2
Filesystem Size Used Available Capacity
tera3scsi#dynmet-u2 52G 50G 2734M 95% /mn/anvil/dynmet-u2
hox /# ssh anvil df -h /mn/anvil/dynmet-u2
Filesystem Size Used Available Capacity Mounted
tera3scsi#dynmet-u2 52G 23G 30G 44% /mn/anvil/dynmet-u2
As you can see --delte removed about 27G files on this filesystem alone.
