We are building a new NFS box and we need to transfer the data from the old NFS
box to the new one. We are talking about 1TB of data. We ran into some
problems using the standard methods so I need to know if there are any better
solutions out there.
Systems are:
Old NFS = 1xE3500, Sol 2.6, 6xA5200 arrays, GigE, SDS to manage disks.
New NFS = 3xE3500, Sol8 0202, 6xA5200 arrays, GigE, SDS
What we have tried and problems.
1) Mount old <-> new
# tar cf - . | (cd <newdir> ; tar xf -)
Problems; A) Have to deal with NFS overheard and getacl calls. (We could
probably get better performance if I new how to extend the NFS
cache timeout.)
B) tar chokes on file/pathnames over 100 chars
C) we get this dubiuos error; "tar: <filename>: Value too large
for
defined data type"
2) Mount old <-> new
# find . -depth -print | cpio -Ppdm <newdir>
Problems; A) Same as A above
B) We get this error; "cpio: <filename> :failed to set acl, errno
22,
Invalid argument"
C) "find" gives us this error; "find: cannot open <file>: Value
too
large for defined data type"
3) "rcp" won't keep owner/group
4) "cp" won't do links
Does anybody have some suggestions?
