Quota loopback test

 

Sometimes should be useful to test quota subsystem.

Prepare testing drive

cd /tmp/

dd if=/dev/zero of=/tmp/disk.img bs=1024 count=20000

mkfs.ext3 -m 0 -L test /tmp/disk.img

mkdir sandbox

mount -o loop,rw,usrquota /tmp/disk.img /tmp/sandbox

OR jurnaled quota

mount -o loop,rw,usrjquota=aquota.user,jqfmt=vfsv0 /tmp/sandbox

Turn on qouta

quotacheck -c -v /tmp/sandbox

quotaon -vu /tmp/sandbox

Copy sample data

cp -ax /bin/ /tmp/sandbox/

ls /tmp/sandbox/bin/

setquota -u root 10000 15000 1000 1500 /tmp/sandbox/

repquota /tmp/sandbox/
