hi
I have a lvm setup with 4 hard disks in total 2TB size. Reiserfs is the file system used. Well coming to the problem.
One of the hard disk has around 130 badblocks. I ran badblocks against the disk which is /dev/sda and it has given the block entries which are corrupted in a file.
What is the best solution to fix this issue. I have a huge database running on that server which doesnt want to start due to this isssue. After doing little search i found that if the problem is on a single hard drive with ext2 file system
The blocks exist on the sda4 partition on my case
fsck -t ext -l badblocks-logfile /dev/sda4
should fix the issue
if its reiserfs then
reiserfsck -B badblocks-logfile /dev/sda4
should i do the same with lvm and will it work fine ? what am worried is if am going to attempt the above step will it disturb the current lvm setup or is there any other bestway to do it.
I did come across another document which i couldnt follow the first step itself.

Any help would be much appreciated.
