Hi all, We're running gpfs 3.5.0.12 (5 total nsds & quorum servers, 2 nsds running samba), sernet-samba 4.1.4-7, and ctdb 1.0.114.7-1 and trying to get transparent failover to work from a windows 8 client. We have ctdb failover working, i.e. if I run mmshutdown on one of the nodes the IPs failover in a few seconds after the GPFS mount is unmounted. For our transparent failover test, I

Hi, I am setting up ctdb samba, and have hit a brick wall trying to solve the following issue. 1. getent does not retrieve the list of domain users or groups (wbinfo works fine) I'm not sure what I'm missing but I've almost spent the whole day trying to resolve this one and haven't made any progress :-( Any help or suggestions are appreciated My configuration is

Hi All, Are there any special CTDB/SMB configuration settings/dependencies to manage Winbind across CTDB managed servers authenticating via Active Directory(AD)? An example would be Samba's IDMAP backend for Winbind: RID vs. AD or tag Winbind to a primary CTDB node and point other nodes to authenticate from AD via proxy primary CTDB node? /etc/sysconfig/ctdb on all nodes is as follows:

Hi Can anyone advise me on "kernel oplocks" in a ctdb cluster. I have a ctdb (GPFS is the parallel file system) setup that uses samba (3.5.8) for cifs and IBM CNFS for NFS. Reading the documentation on kernel oplocks it seems to me that I can export the same area via samba and NFS with "kernel oplocks = Yes" . My logic is that IBM CNFS has shared NFS locking

Hi, in the following scenario I've got the Problem of "STATUS_SHARE_VIOLATION". Client A (with User 1) copies a file to share X. (with: DENY_NONE 0x120196 WRONLY NONE) Client B (with User 1) reads this file from share X (with: DENY_NONE 0x120089 RDONLY NONE) Now Client C (with User 1) wants also to read this file from share X and gets the STATUS_SHARE_VIOLATION.

Hi , I have set up a 2-node CTDB cluster serving NFS and CIFS authenticating Windows and Linux users via Active Directory. The setup works fine, except only one server in the CTDB-cluster is able to join the AD domain at a given instance. If you manually add the other server into AD, the already connected server gets disconnected. There is no specific error message logged in /var/log/message or

Hi everybody, I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not understand some points. It is possible to run the CTDB defining it under services section in cluster.conf but running it on the second node shuts down the process at the first one. My CTDB configuration implies 2 active-active nodes. Does CTDB care if the node starts with clean_start="0" or

Hi Samba, I hope you are doing well. I run a cifs / nfs CTDB clustered NAS solution, and I find that when I reboot any of the nodes in the cluster, I must re-export the nfs mounts so they show up properly. Perhaps this is a general linux nfs bug and I am barking up the wrong tree, but I haven't found any problem / solution mentioning this as of yet besides my own known workaround

I have been running ctdb on our cluster for ~6 months to serve a gpfs filesystem over nfs. It has been running a treat :) ! Recently the servers were upgraded to redhat 5.7 and ctdb-1.0.112-1.el5 is part of the package list. Since the upgrade the log file is filled with messages 2011/10/04 12:35:37.933801 [ 1779]: basename: missing operand 2011/10/04 12:35:37.933850 [ 1779]: Try `basename

Hi All, My site has two separate clustered Samba instances (managed by two independent CTDB instances) running over GPFS. In the last couple of weeks, we have seen a recurring issue that causes the `smbd` process in *one* of these instances to become unresponsive (as seen by CTDB), which results in flapping of CTDB and multiple IP takeover runs. The symptoms that we observe are: 1) Samba

Hi everyone, I'm sorry if this has already been covered somewhere, but I've had a look and can't find it. Also if there is a better place for this question, please let me know. I know that the CTDB documentation states that only NFS2/3 are supported with CTDB but what I'd really like to know is why NFS4 won't work and if NFS4 support is planned for the future (timeline?).

We have a three-node ctdb/samba cluster (8x Sandy Bridge cores + 64GB RAM each node) running on top of GPFS 4.1.0.8, serving 5-600 CIFS clients. We use sernet-samba-4.1.6 with ctdb 1.0.114 on Centos 6.6. Unfortunately the administrator who originally installed the ctdb/samba solution has left some time ago, and we are still learning it. Users are reporting intermittent "latency"

Hi, last weekend I've updated samba and ctdb on my 2-node cluster. Samba is now on 3.5.6 (from 3.3.4), ctdb on 1.0.114 (from 1.0.84). Both installed from repo via yum and ctdb-packages. After restarting both nodes everything was fine, we could access files on the cluster. On monday I noticed that the nodes didn't had their initial adresses: Node 1: hostname dscln01, public IP

I have been working on a CTDB cluster on and off for a while now. I had it working great for a while. THen I decide dthat I wanted to change the configuration of my replicated volumes. I changed my DRBD configuration to match my desired configuration. Now I can get the CTDB to work quite right. I am able to join the cluster to the domain without issues. I can also list my ad users and groups using

Hi I'm encountering an error with some of my Windows clients when using CTDB and samba to access a GPFS hosted share. We see the following error all the time.

Hello Volker, I was able to get those level 10 logs - spitted by machine. Unfortunately I don't know how attachments behave - Groupwise seems not to be happy with those - so I try the redundant way: Here are the logfiles for this event (only one machine, one try): https://www.bitmammut.de/WDR/log.klnmszap32 In this file there are about 3 occurrences of the

Hi all, At some point recently my customers can no longer see GPFS snapshots under the Windows Previous Versions tab. It simply says "No previous versions available". If a fileset is exported with the flag "force user = root" then Previous Versions *are* displayed. [2016/07/06 10:07:35.602080, 3] ../source3/smbd/vfs.c:1322(check_reduced_name) check_reduced_name:

Hi - I was wondering if any of you may be able to point me in the right direction. I am in the process of designing a fairly large fileserver solution in an MS Active directory environment. I have setup and tested ctdb samba, however, after several discussions with a couple of my colleagues, i am now considering a more vanilla flavour of samba. The key features the solution requires are: •

Hi, I am using samba samba3-3.3.4-39, with ctdb ctdb-1.0-69.x86_64, gpfs gpfs-3.2.1 on centos 5.3 x86_64. My problem is that from samba share I can't read file permissions and file ownership, although I'm in "domain admins" group, which has full permissions(rwx) via inherited acl (not user or group ownership). If I'm in a group that owns the file, I can read the permissions,
