I'm facing a boring problem

I've changed the UID of a UNIX user

I hope you had a good reason - such things cause a great deal of prolonged pain in my experience...

                                and now he is unable

to read in old .snapshot because he is not the owner of old files .

is there a way to perform a chown in .snapshot directories when I try the filer answers the filesystem is readonly ...

That's because snapshots *are* read-only. Really, really read-only!

If this isn't a one-off requirement to be dealt with by use of root privilege (it can't persist longer than your maximum snapshot lifetime after all), then you might consider:

1. Giving him a second account under the old uid for the duration.

2. If the files and directories in the snapshot are group-readable, add the new uid to the old group (this rather assumes you use personal groups).
