dump/restore of a fs with 100 of millions hardlinks
Hi :-)
i have a dump of a backupdisk (~540GB / ext3). The Backups have some 100 millions of hardlinks (backups are created with storeBackup). The OS is linux.
A restore of a directory ended after some days with the errormessage "no memory to extend symbol table"
The restore of the complete filesystem ended with a restore af 8GB data and the message Out of Memory: Kill process 2618 (restore) score 73 and children. Out of memory: Killed process 2618 (restore)."
The testsystem has a debian minimal installation and 650MB Ram. Of course I can try it on an other system and wait some days until I have maybe the same message.
An interactive Restore crashed after some days of waiting :-(
codeexample how I restore the whole FS
# restore rd -f filename.dump
in the /tmp dir, the rstdirfile is 5.7 GB and the rstmode file 560M. Here I have the out of memory problem
codeexample how I restore one directory (with all the files)
# restore -x daten -f filename.dmp
here I have the "no memory to extend symbol table" problem ...
First question: is dump/restore aible to handle this numbers of files?
2nd question: if yes, what I make wrong?
greeting from berlin
