question in MV command (will move work with 100% used directory)
Dear all,

I am facing a issue in MV command, this move is done by our c program. We are moving the file to same directory so basically I think it will be a rename of the inode. So we might not useany extra space then why the move is failing. Does it require space to move the same size of file in same directory???
Code:
mv /amap/data/125m.029  /amap/data/125.029
mv /amap/data/125m.004  /amap/data/125.004
mv /amap/data/125m.020  /amap/data/125.020
mv /amap/data/125m.049  /amap/data/125.049
mv /amap/data/125m.030  /amap/data/125.030

mv: cannot move `/amap/data/125.030' to `/amap/data/125.030': 
No space left on device
Unable to perform move 
Command : mv -v /amap/data/125.030 /amap/data/125.030 "

Thanks,
Arun

Seems to be the same filename 125.030 in that error message. Are you doing something silly like
Code:
system("mv ...");

You can use rename(2) in libc, or link(2) and unlink(2).

no that is my typo, this error is like
Code:
mv: cannot move `/amap/data/125m.030' to `/amap/data/125.030': 
No space left on device
Unable to perform move 
Command : mv -v /amap/data/125m.030 /amap/data/125.030 "

If you do not have "rename", you can use another directory where you know for sure there is enough space available and use it as a temp storage:
Code:
mv /amap/data/125m.029 /FreeDir/125.029
rm /amap/data/125m.029
mv /FreeDir/125.029 /amap/data/125.029

This will take more time due to the extra move, but it will accomplish what you want.

agreed, but my question is will MV require space even though we are moving the same file in same directory with same size, only name is different .

see below i am moving the same size of file to the same directory that too with MV command. so i believe it will replace the inode.For that do we need space ???????

Code:
mv /amap/data/125m.029  /amap/data/125.029
mv /amap/data/125m.004  /amap/data/125.004
mv /amap/data/125m.020  /amap/data/125.020
mv /amap/data/125m.049  /amap/data/125.049
mv /amap/data/125m.030  /amap/data/125.030

mv: cannot move `/amap/data/125.030' to `/amap/data/125.030': 
No space left on device
Unable to perform move 
Command : mv -v /amap/data/125.030 /amap/data/125.030 "

Answer:
YES for the mv command is similar to the cp command, except it copies the file then deletes the original...
