New Ibrix Clients Report "segment.rejected" Errors and

Alerts

Solution ID: 00000080

DETAILS:

Symptoms:

Customer was receiving segment rejected alerts and seg.rejected errors in

/var/log/messages also from a handful of his clients.

Here is a sample error:

Segment.rejected:d9eeb202-36b0-4910-9889-beb67a210ec7, 1|

clientname, date-time

Cause:

<Cause>

Resolution:

When a segment is reported as rejected from a client[s] the Ibrix client is unable

to get to a particular portion/segment of the FS. There are a few checks involved

with troubleshooting this type of issue.

1. Validate from the segment server owner with lvmdiskscan, pvscan and

lvscan that the underlying device[s] are all active and superblk is readable

i.e. tuneibfs -l /dev/vg#/lv# ..

2. If the server does not have issue with mounting the segment move your

attention back to the clients.

3. On the clients experiencing the rejected.segment error; verify the

generation # of the FS matches that which is current on the servers and

FM.

i.e. ibrix_fs -i -f FSNAME

4. output from FM will show generation # also the compare

/usr/local/ibrix/bin/rtool enumfs outputs on the client and servers. Do they

match? In this case they did not and that meant the client[s] did not have

an updated map. Stale maps can cause segment access problems.

In this case we simply had to push a new map from the Fusion Manager /usr/local/ibrix/bin/ibrix_dbck -o -f FSNAME [-h hostlist] :update the file system maps on the specified hosts :with the configuration dbase :takes a few minutes to propagate through the entire cluster *Restart of client may be necessary for subsequent mount attempt of FS segment[s] in some cases. i.e. /etc/init.
