If your "/var/spool/news" is on your /var partition, you may have problems with dump|restore as it may not be able to handle the number of files in the filesystem. If this happens then the only solution I can think of is to 'forget' about your existing news articles and start again (ie. blow away all existing news articles!). This is drastic but may be necessary. Alternatively, your could create a partition on the SCSI drive which is the same size as that on the IDE and simply 'dd' the existing partition across. This means that you then have to figure out how to break up the news tree to use the remainder of your 2 GB SCSI which won't be an easy task. Actually, you would be better off doing this and simply newfs'ing the SCSI disk and mounting it at /var/spool/news, leaving {/,/usr,/var} on the IDE disk. We run a news server like this, but with /var/spool/news on one 4.3GB disk and /var/spool/news/alt on another 4.3GB disk, with / and /usr (also /var) on an 850MB IDE drive. Seems to work quite well, although the 72MB of RAM would appear to be a little on the lite side given the way news thrashes the file systems (it needs/want a HUGE buffer cache!!!). If you really want to keep your existing articles, init the SCSI drive and then try dump|restore'ing your /var partition across to it. Once this is done (assuming it works) you can tidy up by removing those files you don't want on each of the filesystems and then restart your news feed. Could be somewhat of a lengthy process, which is why we just started again when we had to do this same exercise! > > Any help would be appreciated > > thanks > > fabian > > email> fabian@nac.ac.za Tony
