vos_convertROtoRW - Converts a Read-Only volume into a Read/Write volume
vos convertROtoRW [-server] <machine name> [-partition] <partition name> [-id] <volume name or ID> [-force] [-cell <cell name>] [-noauth] [-auth] [-localauth] [-encrypt [<yes|no>]] [-verbose] [-noresolve] [-config <configuration file>] [-help]
vos convertROtoRW converts a read-only volume into a read/write volume. Converting a read-only replica to a read/write volume can often be performed faster than restoring the read/write from a dump file or from tape backup. It is intended to be used when the original read/write volume has been permanently lost due to a failed disk, failed server, or accidental deletion.
vos convertROtoRW assumes that the File Server and partition containing the original read/write volume is inaccessible or the volume itself is lost. vos convertROtoRW will make no effort to remove the original read/write volume from the File Server and partition it is housed on.
After running vos convertROtoRW, if the File Server and partition containing the original read/write volume is restored to operation or the original read/write volume is otherwise recovered, the cell administrator should remove it with vos zap. The original read/write volume will not be accessble to Cache Managers because it will not be registered with the Location Service and it will cause problems if future attempts are made to "vos move"|vos_move(1)> or vos addsite the new read/write volume to the original File Server and partition.
Identifies the File Server that houses the read-only volume that will be converted. Provide a fully qualified host name, an IP address or UUID as reported by vos listfs.
Identifies the partition on the File Server named by the -server argument where the read-only volume is to be converted.
Provide the partition's complete name with preceding slash (for example,
/vicepa) or use one of the three acceptable abbreviated forms.
Specifies either the name of a volume including the
.readonly extension or ID of the readonly volume to be converted.
vos convertROtoRW is a destructive operation that can result in the loss of user data and leave the state of the File Server housing the read/write volume out of sync with the Location Service. Provide the -force switch on the command line to avoid a confirmation prompt.
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see vos.
Assigns the unprivileged identity
anonymous to the issuer.
Do not combine this flag with the -localauth flag.
For more details,
Obtains an authentication token using the server encryption key with the highest key version number in the local /etc/yfs/server/KeyFileEx file. The resulting token never expires and has Super User privileges. Do not combine this flag with the -cell argument or -noauth flag. For more details, see vos.
Use the calling user's tokens from the kernel or as obtained using the active Kerberos ticket granting ticket to communicate with the Volume Server and Location Service. This is the default if neither -localauth nor -noauth is given.
Since this option is the default, it is usually not useful for running single command line operations. However, it can be useful when running commands via vos interactive or vos source, since otherwise it would be impossible to switch from, for example, -localauth back to using regular tokens during a bulk operation.
Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear.
Enables or disables encrytion for the command so that the operation's results are not transmitted across the network in clear text.
Shows all servers as IP addresses instead of the reverse DNS lookup hostname.
-noresolve useful when troubleshooting
no such volume and
volume moved errors.
Set the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.
Prints the online help for this command. All other valid options are ignored.
The following example converts the read-only volume test3.readonly in partition vicepb on server1 to a read-write volume:
% vos convertROtoRW server1 b test3.readonly
The issuer must be listed in the /etc/yfs/server/UserListExt file on the File Server specified by the -server argument and on each Location Server. If the -localauth flag is included, the issuer must instead be logged on to a server with an account capable of reading the /etc/yfs/server/KeyFileExt file.
