Is there any update on this? I'm experiencing the same issue on Proxmox 4.1, kernel 4.2.8-1-pve, DRBD 9.0.0. My kernel panic log is identical to the one posted above, same error in lru_cache.c:571. What's best option for me to now? Upgrade to 9.0.1 or downgrade to 8.4? Upgrade to 9.0.1: @Lars, was this fixed in DRBD 9.0.1, so I could ask Proxmox guys to build a kernel with this DRBD version (or trying to build it by myself)? Downgrade to 8.4: @Francois: I suppose you've built DRBD 8.4 by yourself. How have you downgraded disk metadata from 9.0 to 8.4? Did you discarded everything (I mean the metadata) and started from scratch? Thanks both for your help. > Hi Lars, > > Thanks for your analysis ! > > If it can be of any help, we downgraded (module downgrade and metadata > downgrade, nothing else touched, even drbd configuration) this cluster > to DRBD 8.4 and after some heavy stress tests we have yet to make it > crash while it would take around only 10 minutes to crash it on DRBD > 9.0. > > version: 8.4.7-1 (api:1/proto:86-101) > GIT-hash: aff41b8a77838faac8f4e8f8ee843e182d4e4bcc build by > root at sd-84686, 2016-01-17 20:32:22 > 0: cs:Connected ro:Primary/Primary ds:UpToDate/UpToDate C r----- > ns:798510236 nr:54885336 dw:853395572 dr:54193620 al:630522 bm:0 > lo:0 pe:0 ua:0 ap:0 ep:1 wo:d oos:0 > > Best regards, > Francois
