hi all!

i am trying to mount an online harddisk via webdav to backup my home directories. during copying data to the drive i get these messages:

Code:

can somebody explain these messages to me? i assume that webdav is caching files that can not be copied just in time and tries to copy them later. am i right with this?

thx & greets

Edit the davfs2.conf and increase the cache size.

hi!

after some further googling i found out, that the message is due to the need of an higher amount of file cache. default cache size is 50mb and webdav caches files to /var/cache/davfs2/ if they can not be uploaded just in time and uploads them later.
so i conclude that writing performance of the online harddisk is not as good as thought :(

thx for the hint chiefbag...
