We currently go with the "old" way: the users do the up- and download as told in the last years so we dont have to change permissions or the server software and next year we may change the system totally.

Perhaps we can suggest permissions that would do what you want? Thanks Tris, thanks Peter, the goal is, that the FTP server is a Dropbox for Alice, so she can upload files and folders and is not able to see the uploaded files (drwx-wx--- for the main older). Bob should be able to rename the files and folders by ftp. (and of course be able to download them.) If this is not possible with the standad permissions, I'm fine, in the past Users did not try to upload folders and others did not rename ...Than we look for an other workflow.

The permissions for the upload folder are drwx-wx--- and the owner is Bob group is ftpuploadgroup Alice is member of that group, but should only drop files in.

[CentOS] vfstp and renaiming of files with ftp client
Hi, I have a vsftp server and two users for up and download. If user Alice uploads a file, the owner is set to Alice as expected "-rw-r--r-- alice ftpuploadgroup" Now Bob can login to the same folder and is able to rename the uploaded file. Bob can also rename an uploaded folder, but can't rename a file in that folder I'm confused, as I don't get why this is possible at all. Some vsftp magic? :) Can someone explain that to me?

[CentOS] attempt to access beyond end of device XFS Disks

My assumption was, that the free diskspace should be bigger after that, but from what I get with df, it looks like I'm loosing space. Currently the tgz is saved on the same disk/mountpoint.

There are suggestions to increase the open_files_limit, change/add that to /etc/security/limits.conf and modify the systemd script by hand.

On the server I get messages in the log like svc: 172.17.252.35, port=851: unknown version (0 for prog 13, nfsd) rpc.mountd[1927]: authenticated mount request from The curious thing is, that other directories exported on the same filesysten can be exported. so /home/stuff works /home/students fails. chmode 777 is set, /etc/exports is double checked. nfs/rpc/etc is up and running. selinux & firewall for debugging off.

With a "performance optimized" rsync I get an speed of 15 - 20 MB/s The options I use are: rsync -aHAXxv --numeric-ids --progress -e "ssh -T -c arcfour -o Compression=no -x" If I copy files by smb to/from the servers I do get 60 - 80 MB/s, a dd (r/w) on the storages attached gives 90 MB/s on the 1Gbit ISCSI (Source Server) and up to 600MB/s on the 10Gbit ISCSI (Destination Server) storage. Both servers have plenty of memory and cpu usage looks low. Currently we dont use jumbo frames. Network over all usage is moderate to low. There are no special sysctl tweeks yet in use. As mentioned, I'm confused that even with SMB I do get 3 to 4 times better performance. Any hint and suggestion to track that problem down is welcome! Thanks and best regards .

[CentOS] Ext4 mess .... and EXT4-fs error (device sdc): ext4_mb_generate_buddy
Hi, I'm faced with a very strange behaviour: Centos 6.5 server, Hardware ISCSI HBA from Emulex OneConnect, most recent drivers and firmware from emulex installed. Directly attached a 10G ISCSI Storage from QSan. Two Raid volumes, Raid 5, 8 Disks each at 2 TB so 14 TB each logic raid volume. Both volumes are logged in and usable as sdb and sdc to the server. Formatted with ext4 -m 0 -v /dev/sd... Now I copied about 600 GB from an old server to one of the new volumes. No problems at all. But moving other data from the old server to the second volume shows the error in the logs: EXT4-fs error (device sdc): ext4_mb_generate_buddy: EXT4-fs: group 2592: 0 blocks in bitmap, 24544 in gd group grows by 16. But the more strange thing I realised today is, that all the data on the first volume (on sdb) shows up on sdc as well + the new data too. Now I'm totally confused and currently there are no more messages in the system log. The files on sdc don't show up on sdb! If I do e.g. a md5sum on the files on both volumes they are the same as is the contents of e.g. some textfiles I checked. May be someone has an idea what might cause a) the error and b) why dose the data from sdb also shows up on sdc? b) also occurred also with the original redhat/centos driver for the ISCSI HBA. May be I have to use partitions and not the whole device or LVM, ... xfs? Other storages from Qsan dont show that problem and other storages with bigger filesystems or e.g. xfs are o.k. too. confused regards .

[CentOS] suggestions for large filesystem server setup (n * 100 TB)
Hi, over time the requirements and possibilities regarding filesystems changed for our users. currently I'm faced with the question: What might be a good way to provide one big filesystem for a few users which could also be enlarged; backuping the data is not the question. Big in that context is up to couple of 100 TB may be. O.K. I could install one hardware raid with e.g. N big drives format with xfs. And export one big share. Done. On the other hand, e.g. using 60 4 TB Disks in one storage would be a lot of space, but a nightmare in rebuilding on a disk crash. Now if the share fills up, my users "complain", that they usually get a new share (what is a new raidbox). From my POV I could e.g. use hardware raidboxes, and use LVM and filesystem growth options to extend the final share, but what if one of the boxes crash totally? The whole Filesystem would be gone. hm. So how do you handle big filesystems/storages/shares? Regards .

Re: [CentOS] Filesystem labeling confusion or mess up
Hi Cliff, theer is just one path; I rechecked. The storage and server are attached currently direct with one twinaxial cable and just one ip on each side. Multipathing was never configured. I'm confused. Currently I reattached the targets and reformatted the devices. in dmesg I just see one sdb and one sdc. sda is the internal disk and no more disk devices show up e.g. with fdisk -l.

[CentOS] Filesystem labeling confusion or mess up
Hi, I do have an iscsi storage with two raidsets. I'm logged in to the target and get two devices: /dev/sdb and /dev/sdc.

Hi, we have to setup a server which gets a copy of all messages send and received by our mailserver as a 1:1 copy. Mails send to multiple recipients should be calculated and saved per user. (great if you usually have lost of mails send to groups of people.) So no dedublication should be used here. (e.g. save the message and refer the different recipients to it.)

[CentOS] Intel 10G X520-2 and iscsi storage poor performance
Hi, we have a storageserver (Centos 6.4) with a dualport Intel 10G X520-2 Adapter. A QSan P600Q-D316 Storage is configured with 8*SATA Drives raid 5 for test, connected trought a Cisco UCS 6100 Series Fabric Interconnect 10G Switch. I formated the storage with ext4 defaults, one volume and got r/w rates about 10MB/s some up to 40MB/s VERY POOR So we returned the storage to our dealer and they tested the hardware and did some IO Meter Test with VMware ESXi 5.1 Server -> virtual Windows 2k8-R2 on the Qsan Storage. The VM did some r/w IO Meter Benchmark up to 1000 MB/Sec. Better. Hardware looks o.k. Than they installed a Windows 2k8-R2 server and attached the QSAN. The r/w speed is about 400-500 MB/s. After that the dealer installed a Centos 6.4 as I did and the r/w performance is back to our results up to 40MB/s What the hell? Are the default driver and settings so bad? I know and researched a lot of tuning options like buffers, new drivers etc. We did not check that for now, but are'nt there some defalut values and settings which apply as well to be much faster? Or in other words, are some realy simple hints and suggestions to a) debug / find the bottleneck and b) to increase the performance to the same level as windows? Thanks a lot for any help and feedback .

[CentOS] to lvm or not to lvm - why/when to use lvm
Hi, I was wondering, why/when it is useful or when should I avoid to use LVM. I think the big advantage of LVMing is if you modify (rezising, ...) disk and filesystem layouts "a lot". Are there any real pros or cons for following situations regarding e.g. management and speed? e.g.: I do have a server system raid for which the disk layout will not change; e.g. /var /usr /home will not change much in size. OR I do have some file storage shares (iscsi raids) up to some TB each on one big storage device. Sometimes (e.g. after a server crash) it is useful to remount the storage to a different server. Should I use LVM on the iscsi storage volumes? Any suggestion and comment is welcome . Regards .

[CentOS] looking for sssd basics and simple config with existing ldap centos 6.3

My question: "rpm -ql sssd" shows a config in /etc/sssd/sssd.conf, but this file dose not exist on my system. (May be some how a packagebug?) Dose anybody has a working example file to share with me?

Im not yet familiar with it, but found some postings in the web and will try to understand it. Or is 'nlscd' just the old school way and SSSD the new one? cheers .

[CentOS] migrating from Centos 5.8 -> 6.3 LDAP Client Config
Hi, I run a Centos 5.8 samba server which uses a separate LDAP centos 6.3 server for user and group authentication. Now we migrate to a new centos 6.3 samba server and I'd like to know how do 'ldapify' that new server the best way. I'm a bit confused if I can use the same nss setup like on the current old server or how and what to configure to go with SSSD? May be someone can point me to a good how to or has some hints/suggetions? Thanks and best regards .

[CentOS] sendmail / logwatch relaying issue - driving me crazy
Hallo, *<:-) may be I'm to tired to see the solution, maybe someone can give me a hint? I do have a couple of servers, sending the daily logwatch report to a central support email account. Some servers do have DNS A and CNAME records. On my mailserver relaying for the servers is allowed. Only one server drives me crazy, getting user unknown or releaying denied messages. Any idea, how to debug this issue? I'd be glad to fix this as a christmas gift. I could provide logmessages of course.

[CentOS] DHCP failover ... Some questions.
Hi, I plan to reorganise our IP management and I'd like to implement a slave DHCP server. Right now we assign IP addresses based on the ethernetadress of a client 1:1. The tutorial here [1] is simple and looks like the thing I need. I do have a lot of subnetworks and my cisco router has an DHCP helper address set. I know I'll have to add the second dhcp-server address. My questions now is: Dose the dhcp-slave syncs the dhcp data from the master? Or do I have to copy the data to the master AND slave? Any other sugesstions or comments?

[CentOS] how to set up pam_oddjob_mkhomedir (samba and ldap)?
Hi, I do have a samba server up and running and users are authenticated by ldap. Login to the samba server works as long as the user has a home directory. Now if I create a new ldap entry for an user I'd like to use pam_oddjob_mkhomedir to create a home directory if it dose not exist on login. But something fails on my system. I followed the redhat faq http://kbase.redhat.com/faq/docs/DOC-3973 which may be wron according to that bugzilla entry. https://bugzilla.redhat.com/show_bug.cgi?id=429524 So I added sessionoptional pam_oddjob_mkhomedir.so skel=/etc/skel/ umask=0022 to /etc/pam.d/login using all other default settings and configs using the rpms provided by redhat EL 5.5 / Centos 5.5 rpm -qa|grep oddjob oddjob-0.27-9.el5 oddjob-libs-0.27-9.el5 the services are restarted, there are no errors in the log except from samba, that the login from the user fails because of the missing home directory.

[CentOS] Samba and ldap failover - RH / Centos problem?
Hi folks, I recently got my ldap master slave samba test environment up and runing. samba-3.0.33-3.15.el5_4.1 openldap-2.3.43-3.el5 The ldap systems sync fine, samba users are authenticated by each server seperatly if I set tham in the samba conf. E.g. passdb backend = ldapsam:"ldap://ldap2.filmakademie.de"; and passdb backend = ldapsam:"ldap://ldap1.filmakademie.de"; work. passdb backend = ldapsam:"ldap://ldap1.filmakademie.de ldap://ldap2.filmakademie.de"; works as long, as ldap1 is up. If ldap1 is down, no authentication / switchover to ldap2 is done. I've googled, looked up the samba wiki and finaly I found a posting Fedora 4 related to probems with an ldap_initialize() function ... So my question, are ther any known problems or what may I check/debug?
