[Kernel-packages] [Bug 1906542] [NEW] echo 1 >> /sys/module/zfs/parameters/zfs_max_missing_tvds says premission error, unable to reapair lost zfs pool data
Public bug reported: root@jonipekka-desktop:~# echo 1 >> /sys/module/zfs/parameters/zfs_max_missing_tvds -bash: /sys/module/zfs/parameters/zfs_max_missing_tvds: Permission denied root@jonipekka-desktop:~# https://www.delphix.com/blog/openzfs-pool-import-recovery Import with missing top level vdevs The changes to the pool configuration logic have enabled another great improvement: the ability to import a pool with missing or faulted top- level vdevs. Since some data will almost certainly be missing, a pool with missing top-level vdevs can only be imported read-only, and the failmode is set to “continue” (failmode=continue means that when encountering errors the pool will continue running, as opposed to being suspended or panicking). To enable this feature, we’ve added a new global variable: zfs_max_missing_tvds, which defines how many missing top level vdevs we can tolerate before marking a pool as unopenable. It is set to 0 by default, and should be changed to other values only temporarily, while performing an extreme pool recovery. Here as an example we create a pool with two vdevs and write some data to a first dataset; we then add a third vdev and write some data to a second dataset. Finally we physically remove the new vdev (simulating, for instance, a device failure) and try to import the pool using the new feature.

[Kernel-packages] [Bug 1365869] Re: After upgrade to 3.13.0-35.62, rpc.gssd complains about missing /run/rpc_pipefs/gssd/clntXX/info
hi, Real Bug is that NFS logging dose not give clear information wgat's happening and diagnose is hard to do! Problem solved: 1) I finaly found upgrade kernel, after installing it gssapi error message dissapeared and NO ERROR MESSAGES at log's. 2) by useing wireshark I found _kerberos._udp DNS requests and due DNS had not answers I configured BIND9 to publish all kerberos service addresses. I have NFS + MIT kerberos client and apacheDS LDAP + KERBEROS server there is no addministration address at kerberos. joni -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1365869 Title: After upgrade to 3.13.0-35.62, rpc.gssd complains about missing /run/rpc_pipefs/gssd/clntXX/info Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Committed Bug description: The following changes in 3.13.0-35.62: * sunrpc: create a new dummy pipe for gssd to hold open - LP: #1327563 * sunrpc: replace sunrpc_net->gssd_running flag with a more reliable check - LP: #1327563 * nfs: check if gssd is running before attempting to use krb5i auth in SETCLIENTID call - LP: #1327563 are causing rpc.gssd to fill syslog with messages of the form ERROR: can't open /run/rpc_pipefs/gssd/clntXX/info: No such file or directory The problem was discussed last December in https://bugzilla.redhat.com/show_bug.cgi?id=1037793 where the resolution was to include the following three patches: http://marc.info/?l=linux-nfs&m=138624689302466&w=2 http://marc.info/?l=linux-nfs&m=138624684502447&w=2 http://marc.info/?l=linux-nfs&m=138624684502447&w=2 These patches are already in the upstream kernel (since 3.14).

[Kernel-packages] [Bug 1317811] Re: Dropped packets on EC2, "xen_netfront: xennet: skb rides the rocket: x slots"
Crazy idea, could there be situations when sender increases mtu over receiver side? Fundamental question, I tried to understan what ethtool -K eth0 sg off dose in protocoll level can anyone explain, it look's medicine at moment. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1317811 Title: Dropped packets on EC2, "xen_netfront: xennet: skb rides the rocket: x slots" Status in linux package in Ubuntu: Fix Released Status in linux source package in Trusty: Fix Committed Status in linux source package in Utopic: Fix Committed Bug description: Running Ubuntu 14.04 LTS on EC2, we see a lot of the following in the kernel log: xen_netfront: xennet: skb rides the rocket: 19 slots Each of these messages corresponds to a dropped TX packet, and eventually causes our application's connections to break and timeout. The problem appears when network load increases. We have Node.js processes doing pubsub with a Redis server, and these are most visibly affected, showing frequent connection loss. The processes talk to each other using the private addresses EC2 allocates to the machines. Notably, the default MTU on the network interface seems to have gone up from 1500 on 13.10, to 9000 in 14.04 LTS. Reducing the MTU back to 1500 seems to drastically reduce dropped packets.
