how perform a fsck on o logical volume with lvm

[WolverineJR]

i have an 11.0-system. after syslog-entries about defects in the root-filesystem, i wanted to carry out a fsck. but the system told me in single-user-mode that the device (/dev/vg00/lvol3) is in use.
how can i solve this problem?

THX for your tip, but what is when i only have three logical-volumes? and this volumes are:

/dev/vg00/lvol1 mounted on /stand
/dev/vg00/lvol2 is swap
/dev/vg00/lvol3 mounted on /
