raid1 (dmraid) - bad sectors - mount - smartd - complicated!
Hello,
i'm running a server with two disks in raid1.. it seems that some bad sectors have recently appeared on one of the disks.
Sadly it has affected my SVN repo and two important revisions are not accessible anymore! The moment I try to access those revisions the server hangs itself.
Now I am hoping that a good copy of those revisions is still on the second disk (sdb).
I have to keep the server online and cannot do a real maintenance at the time, so is there a way to maybe do a 1:1 image of sdb and mount it elsewhere ? Or while still running raid1 (also without getting the server offline), can I maybe simultaneously somehow mount sdb in read-only and try to access the missing svn revisions and backup it?
Some info (if you guys need any more detailed info, just let me know):
