Hi all, CTDB seems to be needing an underlaying GlusterFS. Would it be possible to declare a second GlusterFS share to host Sysvol data? I have no experience about distributed file systems, so I'm not sure this GlusterFS file system would act as a normal FS (modulo locking process) from Samba point of view when it access to that FS. Then Samba would share this through CIFS these data...

Here is a an encapsulated postscript file and some raw, generic postscript commands to precede and follow the EPS file which puts a message on the page. I have tried this out on two postscript files and it works. NOW, you will have to generate this file for each print job with the appropriate parameters, including, I suppose, the right bounding box, the right location of the text, maybe change

This patch implements XDP batching for vhost_net with tun. This is done by batching XDP buffs in vhost and submit them when: - vhost_net can not build XDP buff (mostly because of the size of packet) - #batched exceeds the limitation (VHOST_NET_RX_BATCH). - tun accept a batch of XDP buff through msg_control and process them in a batch With this tun XDP can benefit from e.g batch transmission

This patch implements XDP batching for vhost_net. The idea is first to try to do userspace copy and build XDP buff directly in vhost. Instead of submitting the packet immediately, vhost_net will batch them in an array and submit every 64 (VHOST_NET_BATCH) packets to the under layer sockets through msg_control of sendmsg(). When XDP is enabled on the TUN/TAP, TUN/TAP can process XDP inside a loop

Hello to the list, We have installed samba 3.0.12 on a solaris sparc server , mainly acting as a backup-server. Now the problem: Some user want to save whole disk-images on their shares which exceed the 2 GB limit. Now my question: Do i need to compile with option "-m64" , or is the underlaying FS responseable for a successful action Kind regards martin schreiber

Hi! I would like to know how well ext3/(ext2) will tolerate underlaying errors (I am planning to use loop-AES backed ext3 fs). So if there is 1024 bytes corruption of data what will be the worst case: - If this data belongs to some file, this part of data(file) has been lost? - If this data belongs to superblock, I have to repair ext3 and use another superblock? - If this data belongs to

Hello GlusterFS users, can anybody give me please his opinion about the following facts and questions: 4 storage server with 16 SATA bays, connected by GigE: Q1: Volume will be set up as distributed-replicated. Maildir, FTP Dir, htdocs, file store directory => as sub dir's in one big GlusterVolume or each dir in it's own GlusterVolume? Q2: Set up the bricks as a collection of

We accidentally left out this error return so it leads to some use after free bugs later on.

Hi. I have two Samba 4 Domain Controller in the LAN network, and I need to join some Windows clients from the DMZ network. I read the document at https://wiki.samba.org/index.php/OpenLDAP_as_proxy_to_AD#Authentication_against_AD_through_openLDAP_proxy and it tells about an OpenLDAP proxy to authenticate some external services through it, but I need to join some Windows clients so I think I

Hi to all does someone knows why Samba 3.0 isn?t possible to mount any Shares from a Server ? i used Domain Authentication and the Share Listing works fine. but when i try to mount the share no Error is logged. the Share is listed in mount but isn?t accessible, just the underlayed Folder. umounting brings up the Error //../.. not mounted ... any suggestions and help would be nice 8) using

I can use the interfaces of AliasAnalysis in my pass, but how to specify the underlaying pass of AliasAnalysis is DSAA? Thanks.
