Hello everyone,
could you please give me an advice how to solve the following problem:
I've got an external 200GB Maxtor USB harddisk. In SUSE 9.3 it is automatically mounted as a subfs hotplug device to /media/usb_disk. It is mounted with synchronous acces (i.e. sync option for mount). However, this sync causes that the writing speed can be only 2MB/s with 100% cpu load (it normally writes about 20MB/s). In SUSE 9.2 I figured out that when it is mounted without sync, the performance is OK (i.e. 20MB/s writing). I have modified /etc/hotplug/hotplug.subfs.functions (i.e. deleted 'sync' from the mounting line there) and after that all worked fine. But in SUSE 9.3 (which I currently use) no matter what I change in /etc/hotplug/hotplug.subfs.functions, the USB disk is always mounted 'sync' (with that horrible writing performance). I understand that it's got something to do wit HAL, but I desperately need to mount the USB disk without sync. Can anyone tell me how to do that? (or even better - how to make sync mounted usb disk write faster than 2MB/s?)
Thank you very much in advance

Try replacing sync with async, see "man mount". Regards Sid. -- Sid Boyce ... Hamradio License G3VBV, Keen licensed Private Pilot Retired IBM Mainframes and Sun Servers Tech Support Specialist Microsoft Windows Free Zone - Linux for all Computing Tasks
