There is an on-error event handler. Mine sends me email if verify fails (runs weekly, one resource each of M, Tu, W, Th nights). Dan In my Global "handlers" section: out-of-sync "/usr/lib/drbd/notify-out-of-sync.sh <myemail>"; -----Original Message----- From: drbd-user-bounces at lists.linbit.com [mailto:drbd-user-bounces at lists.linbit.com] On Behalf Of Lonni J Friedman Sent: Wednesday, October 31, 2012 6:02 PM To: drbd-user at lists.linbit.com Subject: [DRBD-user] very large out-of-sync (oos) value yet drbd-overview claims UpToDate/UpToDate I've got a drbd setup with 8.3.11. I ran a manual verify, and once it completed it reported: [23479.620066] block drbd0: Online verify done (total 23136 sec; paused 0 sec; 73748 K/sec) [23479.702176] block drbd0: Online verify found 9651098 4k block out of sync! [23479.745988] block drbd0: conn( VerifyT -> Connected ) [23479.788996] block drbd0: helper command: /sbin/drbdadm out-of-sync minor-0 [23479.839348] block drbd0: helper command: /sbin/drbdadm out-of-sync minor-0 exit code 0 (0x0) [23479.961245] block drbd0: bitmap WRITE of 2763 pages took 34 jiffies [23480.006527] block drbd0: 37 GB (9651098 bits) marked out-of-sync by on disk bit-map. This isn't entirely surprising, as the secondary node was down for a long time due to hardware problems. However, what is surprising is that drbd-overview still reports that everything is UpToDate: $ drbd-overview 0:sdb Connected Secondary/Primary UpToDate/UpToDate C r----- Shouldn't this huge number of out of sync bits cause drbd-overview to report something other than UpToDate for the Secondary node? If not, then how does one actually programattically detect that a verification has failed? Parsing dmesg is going to be a huge kludge, and not likely to be reliable. thanks _______________________________________________ drbd-user mailing list drbd-user at lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user
