What does the '-y' do in the following command?

fsck -F vxfs -y -o full /dev/vgxx/lvolx

Hi Robert,

The -y flag for fsck answers 'yes' to any questions that fsck would ask you while checking a filesystem. Handy if you have already run it once and you know what you will be answering 'yes' to.

I thought syntax was:

fsck -F vxfs -y -o full /dev/vgxx/rlvolx

The actual answer to your question is correct though.

Hi Robert,

A full fsck without the -y option will prompt you for a response if it is not sure the correct course of action, i.e. whether a file should be deleted etc. The choices are [qyn] I think for quit, yes or no. Adding -y simply means "answer yes to all questions".

Cheers,

James.

Would one of those questions be, 'do you want to relocate data on the disk'?

Plus should I do it on the rlvol and not lvol
??? Is this a must always....

I've never seen any questions about relocating data, and I've fsck'd some filesystems that were pretty hosed up. Mostly the questions are about repairing inodes and resetting flags. The trick is to run it with the -n option to answer no to everything and see what the questions are first. Then you can run it with -y to do the actual cleanup.

I can't see that option anywhere. Relocating valid data blocks is not something fsck would do - it should just check the structural data is in sync with the data on the filesystem. It may relocate blocks to lost+found but this wouldn't be the form of the question. Also, I believe using the raw volume is slightly faster.

I *think* that IF during the fsck process, the system exceeds the read retry limit it assumes the block has gone bad & the system may ask if you wish to attempt relocation. But I'm not sure fsck issues the msg - it may be LVM popping up to query you.

Later,
Jeff

fsck -F vxfs -y (stands for running fsck without any prompt, means it takes 'yes' as default for all Q )

Enjoy
