When your Linux virtual servers share certain disks (a common r/o file system) then you must not write to them. If you do, both Linux page cache and MDC may give you out-of-date data and cause data corruption. Just don't write to them. Use some approach where you prepare a new disk and put it in place through directory updates.
Let me emphasise that point, when Rob says "don't write to them," he means "Don't write to them, at all. Not anywhere." If one Linux guest changes so much as one bit in a directory entry, no other guest understands that it's view of the disk is obsolete. -- 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
