Facilità d'uso
•
No alert is generated if the continuous remote replication target becomes unavailable. Confirm
the connection to the target system by issuing a ping command and by inspecting
ibrcfrworker.log.
•
Sparse files on the source file system are replicated unsparse on the target. That is, all blocks
corresponding to the file size are allocated on the target cluster. Consequently, if the target file
system is the same size as the source file system, remote replication can fail because there is no
space left on the target file system. To work around this situation, if the source system contains
large sparse files, be sure that the target file system is larger than the source file system, and large
enough to fit all files in an unsparsed manner.
•
The mountpoint /mnt/ibrix is reserved for remote replication. Hiding or blocking this mountpoint
by mounting anything over the parent /mnt will prevent Run Once replication from working at
all, and the initial domain scan of Continuous replication will fail.
•
When a replication task encounters a file on the target system that was added or changed outside
of a previous replication, the replication task stops and does not replicate the remaining files from
the source to the target.
•
If the target file system is unmounted while an inter-cluster or intra-cluster CRR task is running, the
CRR task will not work properly. Before unmounting a file system, it is a best practice to verify
that the file system is not the target for a CRR task. If the file system is the target for a CRR task,
stop the task before unmounting the file system.
Data retention and validation
•
The ibrix_reten_adm command fails if the date string specified with -e contains spaces. As
a workaround, use the following command to enter date strings containing spaces:
/usr/local/ibrix/sbin/ibr_reten_adm -e expire_time -f FSNAME -P PATHLIST
•
The ibrix_vs_snap command cannot delete a block snapshot file system that is enabled for
data retention. Instead, use the ibrix_fs command with the -R option. For example:
ibrix_fs -d -f block_snap_ifs2_1 -R
•
When the GUI or ibrix_reten_adm -r is used to remove a legal hold from a file, it displays
invalid errors about autocommit; however, the command completes successfully. You can ignore
the error messages.
•
Directories are not supported in the path list for the ibrix_reten_adm command. However,
the command does not display the correct error message when the path list includes a directory.
•
PDF reports do not display on Internet Explorer with Adobe Reader 10.1.2 installed. Reports
display properly with earlier versions of Adobe Reader or with other supported browsers.
•
The ibrix_reten_adm -e command fails for WORM files that are not retained. If a WORM
file is not retained (either it has never been retained, or it was retained but its retention period
has expired), use the touch command to set its last accessed time (atime) forward to the desired
expiration time. The file will then be retained until that time.
•
PDF reports cannot be generated from the GUI when using Windows Internet Explorer 8. To
display the PDF, use one of these options:
◦
On the browser, right-click in the white border surrounding the grey area, and select View
Source. Locate the src= line in the source. For example:
src="/fusion/reporting/retention/retention_ifs1.pdf#scrollbar=0"
width='100%' height='100%'/>
Prepend https://
the browser. Using the previous example, you would enter:
