I wanted to use something like "<tt>debugfs -f -w -R 'set_mmp_value seq 1234' /dev/MDT</tt>" or "<tt>... 'feature ^mmp' ...</tt>" to reset the e2fsck sequence number, but it was not possible to open the filesystem as it continually returned an error when trying to open it in write mode:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># debugfs -f -w -r "set_mmp_value seq 1234" /dev/sdc MMP: e2fsck being run while trying to open /dev/sdc </pre> </div></div> LU-17117
