Hi Michele,
thank you for you answer, but:
I've tried also the second form of "mount" command - i.e:
"mount -n -o remount -t reiserfs /dev/sda1 /"
without succes - I became only error message:
"Input/output error"
There was an SCSI-error in dmesg and it was not possible to read or write
anything on the system then ...
Regards
Nikita Michalko
