What's the maximum file size for a file to be dumped by xfsdump?
xfsdump doesn't (really) have a maximum file size limitation. There
is a maximum file size defined in xfsdump/dump/content.c but it is set
to the largest theoretical file size, 18 million terabytes. The
definition is defined in bytes:
/* max "unsigned long long int"
*/
#define ULONGLONG_MAX 18446744073709551615LLU
Obviously this maximum limit is impossible to hit, which is why I say
xfsdump doesn't have a max file size limit. You should be able to
dump the biggest possible file you can create.
There is, however, a command line option (-z) to set a maximum file
size for your dump. This option allows you to specify a maximum file
size, in kilobytes. Files over this size will be excluded from the
dump.
When running a dump with "xfsdump -F -e -f /local/backup/weekly/sdb3.dmp
-l 0 /dev/sdb3" I get the message, "xfsdump: WARNING: could not open
regular file ino 4185158 mode 0x000081b0: File too large: not dumped".
The file in question is 5.0 GB.
