vos_lock - Locks a volume
vos lock -id <volume name or ID> [-cell <cell name>] [-noauth] [-auth] [-localauth] [-encrypt [<yes|no>]] [-verbose] [-noresolve] [-config <configuration file>] [-help]
The vos lock command locks the indicated volume, blocking any operation that requires a modification to the volume metadata. Volume locks are acquired by most vos command to ensure that the volume cannot be modified by another vos command simultaneously. Locking a volume does not prevent Cache Managers from accessing or modifying the volume content.
Cell administrators can use the vos lock command to prevent the execution of vos commands. Cell administrators that lock a volume must remember to vos unlock the volume at a later date.
The lock applies to all of the volume versions (read/write, read-only, backup) and not just the one specified with the -id argument.
To unlock a single volume, use the vos unlock command. To unlock all (or some) of the locked volumes, use the vos unlockall command.
The vos lock command will lock a volume preventing the operation of most vos commands on the volume.
Specifies either the complete name or volume ID number of a volume of the any of the three types.
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/KeyFileExt 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 command locks the volume
% vos lock user.terry
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.
