hi
we have a cluster server which consist of sql databases for our sharepoint farm sites.
server : w2k3 r2 sp2
currently, we having issue with incremental backup not successful. we are using a 3rd party backup software to run backup. for the 1st full backup was successful but after that an error appeared when to perform incremental backup. check at event log, the event id:17,Source: arcflashvoldrv .
problem occured when we'd expanded 1 of volume fr 3 tb to 7tb. earlier, we had put about 15%-50% for vss (3.63 tb) on the same volume itself , then reboot the server.
prb happen again when run incremental backup, but this time wt error event id: 20, source volsnap :The shadow copies of volume e: were aborted because of a failed free space computation
total size : 7.26 tb
free space : 4.13 tb
when perform vss list writers, notice that got 2 writers which failed status. they are
Writer name: 'Cluster Service Writer' state : [10] failed
WMI writer State : [10] failed
i have come across 1 of Microsoft article to download hotfix as per kb 887827, but not sure whether it will suitable @ solve the problem besides the above writers failed. may i know what should be done to correct the writers as well? i dont think its due to the backup software issue, because for full backup was successful, as well as verify backup after performed restart server. kindly guide me because im newbie in windows server clustering, etc. something related to pool allocation?etc.
tx in advance for the offer help.
