Currently running WAS on zOS and we are migrating to a zLinux system. There are about 10 mod-9s (60-80 GB) worth of WAS data a lot of Docs and PDF created from data mining apps that need to be migrated off of zOS, WHILE MAINTAINING ACLs AS WELL AS PERMISSIONS. That's the big key, getting the ACL's to go with the data. What we have tried: Exporting the zOS HFS as an NFS, mounting the filesysem to zLinux and pulling the data. The ACLs do not come across. There has been some debate as to whether v4 of NFS can support ACLs, but have no idea how to configure NFS on zOS to do so. Mounting a zLinux NFS share to zOS USS. We have not been able to successfully mount the zLinux share. We have gotten a wide range of errors and even to the point where it appeared we did get successful mount (no errors returned), but could still not see the data. There is concern to begin with about zipping up an HFS of this size (using PAX or STAR, which are archiving programs that will maintain ACLs) without overloading the machine and failing anyways. Simple file transfers, scp, ftp, etc. does not seem to maintain the ACLs either. Again, thanks for any help,
My first concern would be whether the ACLs can be expressed in Linux, and what preparation needs to be done. An ACL to grant access to group FRED might not transfer if FRED does not exist, I would also wonder (but you might know the answer) whether there is character-set translation to be done. I have not used pax or star, but I have used tar (and maybe cpio) to create files some gigabytes in size. linux has no limits at 2 Gbytes or 4 Gbytes. On zSeries, I would not compress them. It's possible to copy host to host using tar: tar clC /www | \ssh example.host tar xpC /copied/wwww I expect pax and star can do this too. the backslash prevents the use of any alias you might have for ssh, I got bitten once as I execute "alias ssh='ssh -t'" when I login. On my RHEL5-clone, rsync claims to preserve extended attributes. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 You cannot reply off-list:-) ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
