creating a share with vba on a filer
by Ulrich Neumann 11 Sep '00

11 Sep '00

we just turned our user-home-shares from a nt-server to a filer. for creating new user-shares, we use a selfmade program in vb. unfortunately this program woun't work now with the filer. neither "c:\vol\nt01\users\username" nor "\\cobfile01\users$\username" is working. there's always the error 2116.(see sub makeshare in attached code) is there anybody out there who has a good idea to solve this problem? greetings from brose GmbH & Co KG Client-Server-Technologien Ulrich Neumann

multiple raid grps in filesystem on filer
by neil lehrer 08 Sep '00

08 Sep '00

hi, i understand that having more than 1 raid grp in a filesystem makes the filer more fault tolerant of a full raid grp failure. so lets say there are two raid grps in the filesystem. if you lose a raid grp [2 drives fail] how do you restore it? i can understand restoring the whole filesystem or a qtree or a dir, but if files and dirs can go across more than 1 raid grp in a filesystem what is the advantage of short restore of the broken raid grp? how do you put back just that raid group? i know you can replace the bad drives and then recreate the group but how do you restore the data for just that raid grp? thanks
