| 2 | .SH NAME |
|---|
| 3 | attachtab \- attached filesystem table |
|---|
| 4 | .SH DESCRIPTION |
|---|
| 5 | Attach maintains an printable text database of all successful attaches |
|---|
| 6 | in the \fIattachtab\fR. It uses this file to determine the current status |
|---|
| 7 | of a filesystem (attached, being attached, being detached) and to |
|---|
| 8 | retrieve information about it. The following information is stored in |
|---|
| 9 | /usr/tmp/attachtab: |
|---|
| 10 | |
|---|
| 11 | A version number |
|---|
| 12 | .br |
|---|
| 13 | An explicit flag |
|---|
| 14 | .br |
|---|
| 15 | The status of the filesystem (attached, being attached, or being detached). |
|---|
| 16 | .br |
|---|
| 17 | The type of the filesystem (e.g., NFS, RVD, etc.). |
|---|
| 18 | .br |
|---|
| 19 | The \fIHesiod\fR name of the filesystem (or the explicit name when |
|---|
| 20 | -explicit is specified). |
|---|
| 21 | .br |
|---|
| 22 | The name of the server on which the filesystem is located, if the |
|---|
| 23 | filesystem is on a remote host. |
|---|
| 24 | .br |
|---|
| 25 | The server's pathname or RVD locker name for the filesystem. |
|---|
| 26 | .br |
|---|
| 27 | The internet address of the server. |
|---|
| 28 | .br |
|---|
| 29 | The number of directories that had to be created to make the |
|---|
| 30 | mount point. |
|---|
| 31 | .br |
|---|
| 32 | The mount point pathname. |
|---|
| 33 | .br |
|---|
| 34 | The RVD driver number (if the filesystem is of type RVD). |
|---|
| 35 | .br |
|---|
| 36 | The userid of the user who attached the filesystem |
|---|
| 37 | .br |
|---|
| 38 | A flags field. If the lowest bit is set, the the filesystem was |
|---|
| 39 | mounted with the nosuid option set. |
|---|
| 40 | .br |
|---|
| 41 | The mode (r or w) of the filesystem. |
|---|
| 42 | |
|---|
| 43 | \fIAttach\fR and \fIdetach\fR also communicate via temporary files in |
|---|
| 44 | /tmp. These files are used to determine whether or not the status |
|---|
| 45 | field of /usr/tmp/attachtab is accurate. For example, if an \fIattach\fR |
|---|
| 46 | is aborted for some reason, /usr/tmp/attachtab may still indicate that the |
|---|
| 47 | filesystem is in the process of being attached. These files are named |
|---|
| 48 | /tmp/attach.\fIfilesystem\fR, and are deleted as soon as they are no |
|---|
| 49 | longer needed. An advisory lock is kept by the active process on the |
|---|
| 50 | file to indicate that a process really is operating on the filesystem. |
|---|
| 51 | |
|---|
| 52 | .SH FILES |
|---|
| 53 | The location of attachtab can be dynamically configured in |
|---|
| 54 | /etc/athena/attach.conf; by default it is located in /usr/tmp/attachtab. |
|---|
| 55 | It is also commonly placed in /etc/athena/attachtab. |
