oracle zfs unified storage - Kemel konsol komutları

1. Sistem komutlarının neler olduğunu öğrnemek için konsolda;
   maintenance system help
   komutunu vermemiz yeterli olur.


    ZFS disk ünitemizi yeniden başlatmak istersek;

    maintenance system restart

     komutunu vermemiz yeterlidir.

2. Sistemi tamamen kapatmak
zfs-vbox:>  maintenance system poweroff
This will turn off power to the appliance. Are you sure? (Y/N)
Connection to 10.254.254.57 closed.



3. Workflowları listelemek;

zfs-vbox:> maintenance workflows list

Adobe firması linux dünyasından nefret mi ediyor?

Bu gün ubuntu kurdum ve üzerine acrobat reader kurmaya kalktım.
Ne yazikki adobe.com dan ubuntu için acrobat reader indiremedim.

ADOBE LINUX DESTEĞİNİ KALDIRMIŞ!!!!
ESKİ LİNUX SÜRÜMLERİNİDE İNDİREMİYORUZ!!!
 ACABA PDF KULLANMAYI TAMAMEN BIRAKSAK MI?

ADOBE FİRMASININ BU DAVRANIŞINI KINIYORUM....

nfs

RHEL 7 tabanlı(rhel/centos/oel 7 ) sistemlerde nfs'i firewall ve selinux ile kullanabilmemiz için yapılması gereken temel işlemler;
firewalld'ye nfs servislerine izin vermesini sağlamak;

firewall-cmd --permanent --add-service={nfs,mountd,rpc-bind}
firewall-cmd --reload

selinux'e nfs servisinin dosyalara erişmesi için izin vermek;

setsebool -P nfs_export_all_rw on
setsebool -P nfs_export_all_ro on

semanage fcontext -a -t public_content_rw_t "/nfs-share/nfs-yazilabilirdizin(/.*)?"
semanage fcontext -a -t public_content_ro_t "/nfs-share/nfs-okumasina-izin-verilen-dizin(/.*)?"

restorecon /Rv /nfs



nfs kullanırken her zaman mount yerine, /etc/fstab içerisine aşağıdaki gibi yazarak, kullandığımız nfs  bölümünü, sistem açılmasında otomatik olarak sisteme bağlanmasını sağlayabiliriz.

172.16.0.33:/home                      /home   nfs     bg,soft,noatime,nodiratime,rsize=8192,wsize=8192,timeo=14,intr,_netdev 0 0
172.16.0.33:/home/depo2                /home/depo   nfs     bg,soft,noatime,nodiratime,rsize=8192,wsize=8192,timeo=14,intr,_netdev 0 0

Son bir yıl içinde bozulan ikinci disk

Son bir yıl içinde ikici 1 TB seagate diskimde bozuldu.
Önemli bilgilerimin bir kısmını kayıp etsemde, büyük çoğunluğunu testdisk ile kurtarabildim.
 Testdisk programını yazanlara teşekkür ederim.
Bozuk disklerden veri kurtarma ihtiyacı duyarsanız, testdiski kullanabilirsiniz.

http://www.cgsecurity.org/

Seagate disklerine 3 yıldan fazla kullanmamak, 3 yılını dolduran diskleri bozulmasa bile yenisi ile değiştirmek gerekiyor!!!!



Diskin verdiği hatalar ve smartctl programının söyledikleri aşağıda;

Windows ve jumbo paket

Bu gün Windows 2012 sunucusunda disk kullanımında performansı artırmak için jumbo paket boyutunu 9014 yapıyor fakat 1500 byte üzerinde paketleri iletmiyor.
Sorun windows ile birlikte gelen standart intel ethernet kartı sürücüsünden kaynaklanıyor. Ethernet kartı Intel® Ethernet Controller X540-AT2  Intel'in sayfasından sürücüyü indirip yükledikten sonra ethernet kartı 10Gbit ve 9000 byte paketleri iletmeye başladı. Buda gösteriyorki, daima ürün üreticisinin sürücülerini kullanmak gerekiyor. Tembellik edip, sürücüyü ürün üreticisinin sürücüsü ile güncellemezsek, sistemden yeterince verim alamayız...
