Can we migrate from Veritas File system VxFS to AIX JFS2 File System? Please respond to it, Urgent need of info

2 AnthonyEnglish commented Permalink

I don't think you could convert a Veritas VxFS to JFS2, but you could create new JFS2 file systems and migrate the data, for example through database utilities or an OS copy. Worth a support call to IBM.

I just have one question. If I set "Allow internal snapshot" as yes during JFS2 file system creation, how can I make use of these internal snapshot later? Will AIX itself be responsible for these JFS2 file systems recovery by using the internal snapshot automatically?

JFS2 snapshots are not automatic. Of course you can schedule them via the cron. <div>&nbsp;</div> For a good overview of snapshots, see Chris Gibson's developerWorks article http://ibm.co/cDaMun <div>&nbsp;</div> It was written for AIX 6.1, but applies just as well for 7.1. <div>&nbsp;</div>

I just read Chris Gibson's JFS2 snapshot article you recommended. It's useful and answers all my questions. Thank you very much, AnthonyEnglish! :-)
