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

...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 without caring GUP thus it can do batch map flushing. When XDP is not enabled or not supported, the underlayer socket need to build skb and pass it to network core. The batched packet submission allows us to do batching like netif_receive_skb_list() in the future. This saves lots of indirect calls for better cache utilization. For the case that we can't so batching e.g when sndbuf is limited or packet...

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.
