[CentOS] NFS - No lista dos directorios especificos
Estimados. Actualmente, estoy tirando los backups a un server que comparte por NFS los directorios. Me encuentro con un problema, por ahora en dos servidores, en el cual no puedo ver directorios exportados. Server: LaCie 5Big Network (sistema propietario, sin acceso root. http://www.lacie.com/la/products/product.htm?id=10485) Cliente1: root@server [/home/cpbackuptmp]# uname -a Linux fq.dn.net.ar 2.6.18-348.1.1.el5.centos.plus #1 SMP Tue Jan 22 19:16:31 EST 2013 i686 athlon i386 GNU/Linux El problema, radica en que no puedo ver dos directorios exportados, dejandome medio sin terminar el directorio donde tiro los backups, por lo que estoy pasandolos via ftp Existe algun limite en NFS en cuanto a los directorios a exportar? Alguna otra idea por donde puedo buscar el problema/solucion? La verdad, que reconozco que tengo muy poco conocimento sobre trabajar con NFS. -- root@server [/bkp]# showmount -e aaa.bbb.ccc.110 Export list for aaa.bbb.ccc.110: /shares/a* /shares/b* /shares/c* /shares/d * /shares/f * ... /shares/y* root@server [/bkp]# showmount -e aaa.bbb.ccc.110|wc -l 25 Deberia tener 27 directorios exportados. En el LaCie, los directorios fueron creados de la misma forma. De hecho, he creado otros para otros servidores, y se muestran. Tambien probe cambiando el nombre, eliminandolo y volviendo a crear, etc. Tambien reinicie el LaCie. Solucion bananera y argentina en mente: crear un solo directorio, adecuar todos los otros servers y realizar backup en los directorios especificos La verdad, mucho no me convence trabajar de esta manera, pero bue... Ambos servidores, son CentOS 5.9 final (el 3ro con esta version, lo monta perfectamente) Algun limite de la version? -- Diego - Yo no soy paranoico!

Re: [CentOS] Backup of large filesystems >500GB
Or, you can use http://sourceforge.net/projects/ext2read/ (or similar) Copy&Paste: Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents. It can be used to view and copy files and folders. It can recursively copy entire folders. It can also be used to view and copy disk and file -- Diego - Yo no soy paranoico!

Multiple NFS servers, each provides a subset of the messages to the appropriate server with postfix-I, which is the NFS client. Data from the NFS server which host the frontend postfix-I should be mounted with the mail folders are in MySQL. We are looking at replacing some host-s single storage solution matrix of appropriate disk capacity and performance I / O. You can prompt the pros and cons of such a solution? or matrices usually have several times higher performance I / O than single server with SATA drives? Is such a performance I / O is scalable? Do you scale the storage space in the arrays can be "without restrictions "? Thanks! Regards, > > -- > Regards, > > Rajagopal > Google translate :p -- Diego - Yo no soy paranoico!
