42 more Data Servers (DS)s.
52 All DS(s) and the MDS should support NFSv4.2 as well as NFSv4.1.
53 Mixing an MDS that supports NFSv4.2 with any DS(s) that do not support
55 As such, all DS(s) must be upgraded from
60 .Sh DS server configuration
61 The DS(s) need to be configured as NFSv4.1 and NFSv4.2 server(s),
77 jot -w ds 20 0 | xargs mkdir -m 700
100 Alias addresses can be set on the DS server system for a network
123 The DS(s) must all be mounted on the MDS using the following mount options:
207 server, using separate file systems on the DS system
208 for storage of the respective DS's data files.
218 The number of subdirectories in each DS is defined by the
247 which acts as a proxy for the appropriate DS(s).
257 When a mirrored DS fails, it can be disabled one of three ways:
260 operations on the DS.
262 after the DS failure or network partitioning occurs.
264 2 - A pNFS client can report an I/O error that occurred for a DS to the MDS in
270 (Device not configured) that normally means the DS was already
273 there is a problem with a mirrored DS, doing the command is recommended.
275 Once a system administrator knows that a mirrored DS has malfunctioned
279 # pnfsdskill <mounted-on-path-of-DS>
280 # umount -N <mounted-on-path-of-DS>
283 Note that the <mounted-on-path-of-DS> must be the exact mounted-on path
284 string used when the DS was mounted on the MDS.
286 Once the mirrored DS has been disabled, the pNFS service should continue to
287 function, but file updates will only happen on the DS(s) that have not been disabled.
288 Assuming two way mirroring, that implies the one DS of the pair stored in the
290 extended attribute for the file on the MDS, for files stored on the disabled DS.
294 extended attribute on all files on the MDS for the failed DS.
295 This is done so that, when the disabled DS is repaired and brought back online,
296 the data files on this DS will not be used, since they may be out of date.
320 If the disabled/repaired DS is nfsv4-data3, the commands done on the MDS
350 Once this is done, the replaced/repaired DS can be brought back online.
359 Then restart the nfsd to re-enable the DS.
