Hi all, we have on one of our systems a strange DRBD problem. One DRBD resource has lots of "bio_add_page failed" errors which leads to constant resyncs for about one hour yesterday. Today the "bio_add_page failed" errors occured again. All other (10) resources (same configuration) don't have this problem. On top of the DRBD-Device runs a KVM-guests, the backing-device is a LVM partition.
host-z1 is primary, host-z2 is secondary. kern.log on host-z2 looks like this: May 25 18:00:16 host-z2 kernel: [77255.104705] block drbd8: alloc_ee: bio_add_page(s=13979095,data_size=8192,ds=4096) failed May 25 18:00:16 host-z2 kernel: [77255.104822] block drbd8: merge_bvec_fn() = 0 May 25 18:00:16 host-z2 kernel: [77255.104931] block drbd8: bio->bi_max_vecs = 4 May 25 18:00:16 host-z2 kernel: [77255.105011] block drbd8: bio->bi_vcnt = 1 May 25 18:00:16 host-z2 kernel: [77255.105097] block drbd8: bio->bi_size = 4096 May 25 18:00:16 host-z2 kernel: [77255.105175] block drbd8: bio->bi_phys_segments = 1 May 25 18:00:16 host-z2 kernel: [77255.105261] block drbd8: error receiving Data, l: 8216!

DRBD version: 8.3.7 Kernel 2.6.34.6 (64bit) Any help would be much appreciated!
