As a followup to my previous mail.
I have repeatedly tried amrecover with different disks in my config. The
small disk (with original 760 MB, after backup ~380 MB) seems to let me
recover. The bigger disk (original ~ 18 GB, after backup ~9 MB) always
hangs or reboots the server itself. No compression is used, just tar, in
the config.
Does amanda impose a limit on disk size???
Amanda does not, but many OS's do. A common file size limit is 2GB.
Jon, I have done some search for Linux file size. It says:
For ext2/3 and kernel 2.4.x, file size: ~ 4TB, filesystem size: ~ 1TB.
Obviously, it can't be the kernel that imposes this limit. Morever, I
was able to get a dump, using tar, of size > 9 GB. If the OS has a limit
of 2GB, I wouldn't have gotten this far.
I have a feeling that while searching for the specified file to recover,
it somehow exhausts system mem with a size of 9 GB, in only one tar
file. Now that is just a guess, because I don't know how tar searches
for file in its archive.
Anyone ever tried anything that big? in just on file?? and been
successfullly recover it ???
