similar to: Is it fine to store the tdb files in the shared directory to solve the ctdb data synchronization problem?

Thanks very much, Volker. I want to synchronize three tdb files(listed as below) which is relevant to the opened file: 1) brlock.tdb 2) locking.tdb 3) smbXsrv_open_global.tdb These three tdb files are used to realize the durable file handle feature. As what you have said, the performance will be affected if storing these three files in the shared storage. So can I realize the synchronization

Hi all Thanks for your attention. CTDB manages NICs with event scripts. Virtual IP attaches on a NIC as a secondary IP. When noticing the NIC down, CTDB will pull it up. Does any one know how to disable the action? I do not want CTDB pull any NIC up. Does the command 'ctdb disablescript 10.interface' has any unexpected effect? Thanks.

If eth0 holds virtual IP as its secondary IP and I bring down eth0 by command "ifdown eth0", CTDB will automatically pull eth0 up. Sometime it goes wrong. The virtual IP becomes primary IP, and origin primary IP turns into a secondary IP or just missing. If the origin primary IP is missing, I have to run "ifup eth0" though CTDB has pulled eth0 up. CTDB uses “ip link set eth0

HI I have a linux samba server and lists users at this server. and access the folder from the windows7 client. Now i configure a LDAP sever and let samba to use it . But I don’t want clients keeping the connection because I have changed the authentication,clinets need to re-login. So I restart smbd. and it works. Then,let clients reconnect to samba, but it report errors: Windows cannot access

Hi folks I want to print the log in socket_wrapper.c to have a better view of the read or write socket behavior. I find that there are four debug levels: SWRAP_LOG_ERROR SWRAP_LOG_WARN SWRAP_LOG_DEBUG SWRAP_LOG_TRACE So: Where and How to set those debug levels? Where can I find the log? Or: Are there any other ways to print the log?(I

hi Michael： We want to implement the ‘persistent handle’ function under Windows 7(SMB 2.1), which has only local ‘durable handle’. For now my plan is just to synchronize the following files between cluster nodes: smbXsrv_open_global.tdb.0 smbXsrv_session_global.tdb.0 smbXsrv_tcon_global.tdb.0 locking.tdb.0 It probably won’t be completed, so I’m writing to ask for your advice. Any help would be

Hi all http://linux.die.net/man/1/ctdbd. In this page, it says “This directory is local for each node and should not be stored on the shared cluster filesystem”. But why? Thanks for reply. --dbdir=<directory> This is the directory on local storage where ctdbd keeps the local copy of the TDB databases. This directory is local for each node and should not be stored on the shared cluster

Thanks for your attention. First, use local users at samba server, and client login success. [global] workgroup = H3C ONESTOR server string = %h server (Samba NAS) dns proxy = no log file = /var/log/samba/log.%m max log size = 100000 log level = 10 syslog = 0 panic action = /usr/share/samba/panic-action %d server role = standalone server obey pam restrictions = yes

Hi folks I face a problem when using the samba share, Here is the detail: 1) Phenomenon In windows 7, sometimes, I type the samba server ip address and can see the shared folder. (the samba version is 4.3.11) a、However when I try to open the shared folder, it fails with a windows error message like “please check the spelling of the name, or some problem may related to the network”, and

Thank you very much for reply. Our test team insists on simulating network failure by using ifdown instead of just unpluging the cable. I have to modify the event script 10.interface. When noticing a NIC failure, CTDB just marks the NIC down and do not try to pull it up. It seems to work fine. -----邮件原件----- 发件人: Martin Schwenke [mailto:martin at meltin.net] 发送时间: 2016年9月18日 18:49 收件人: Weidong

hi Michael Adam: Thanks for you work on samba. Here I am looking for some advice and your help. I have been stuck in continuous availability of samba 4.3.9 for two weeks. Continuous availability in SMB3 is an attractive feature and I am strugling to enable it. smb.conf, ctdb.conf are attached. Cluster file system is cephfs and mount to /CephStorage client: Windows 8 Pro root at node0:~# samba

Thanks for your reply, Louis However, I am still blocked by this problem now. !-_- I tried to set the samba server as the DNS server and visit the shared folder by input "\\aaa.bb.com" at windows 7 client. In some cases it works and will not fail. However the similar abnormal phenomenon also occasionally happens (especially at changing the authentication, such as local to ldap): 1) I can

Hi folks Recently, I find that the number of the smbd connections may increase if the network is abnormal. And the repeated connections will exist for a long time (which is not accepted for me) So, I modify the following params and shorten the existing time of those repeated connections: TCP_KEEPCNT 3 TCP_KEEPIDLE 60 TCP_KEEPINTVL 15 My concern is that: Are there any

Thanks for your attention, Gaiseric. Sorry , but I had a little confused. Did you mean that the problem was something relevant with the DNS? However in my impression, I might not do anything about the DNS. I have some clues that might be helped: 1) First of all, my samba server version set is "max protocol = SMB2", and the final protocol according to the negotiation result is smb2.10.

Hello to everyone Durable file handles allow a connection to an SMB server to survive a short network outage. An ongoing IO will continue after the client reconnects to the same server (maybe a difference smbd process if the CTDB status is always health during the outage). When crossing nodes caused by virtual IP’s relocating, durable handles will not work apparently. CA feature in SMB3 works

Hi samba-team, I met a problem recently: Problem Description: The connection would be broken when read rate is too big. Environment: Samba 4.3.11 Ubuntu server 14.04 Configuration: usershare allow guests = yes max protocol = SMB3 large readwrite = yes use sendfile = yes aio read size = 1024 oplocks = yes deadtime = 10 aio write behind = true clustering = yes store dos

Well, I have changed the line "map to guest = bad password" to "map to guest = bad user" However the problem still exists: 1) I can pass the authentication and see the shared folder, but when I try to open the folder , it fails with a windows error message like "cannot find the route to the network". It may recover to normal later (means I can open that folder) 2) I

Hi folks I face a problem when creating a samba user, Here is the detail: (1) Phenomenon I have created a linux user q01, Q01, and samba user q01,and then, when I created the samba user Q01,I ran into a problem: I use “smbpasswd –a Q01” to create samba user Q01, command line returned successfully, but in fact the samba user has not been created. I can not query the user with the

hi Michael, Sorry for taking so long to reply, I just get back on vacation. Your advice is very helpful. Our purpose is no IO interrupted with Window 7 cifs client accessing the shared folder when virtual IP taken over by another node. SMB3.0 or newer protocol do meet that demand, but Window 7 cifs client only supports SMB2.1 protocol and previous versions. So we need implement a
