Fwd: how to mount r/w encrypted partition when it is mount ad read-only?

[s m]

hello all
i have an encrypted user partition which is encrypted with geli. user is
mounted read-only. i want to mount it r/w for a short time, copy some files
on it and mount it read-only again. with unencrypted partitions, we can
change mount options. for example if an unencrypted user partition is
read-only mounted, we can mount it r/w by "mount -rw  /usr" command. but
for encrypted partitions this command doesn't work and error "device busy"
occurs.

is there any way to mount r/w encrypted partition when it is mounted as
read-only?

thanks in advance,
sam
