[LU-12809] recovery-small/110k gets stuck at client umount

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.14.0
• Severity: 3
• Assignee: Alex Zhuravlev
• Reporter: Alex Zhuravlev

Description

this happens because umount calls into statfs() which in turn waits for MDS2 stopped by the test:
stop mds2 || error "stop mds2 failed"
umount $MOUNT

statfs() is supposed to be "lazy" as per Andreas's comment in skype, but it is not for connections to MDSs.
