Cpanel kurulu Centos 6.4 serverde en son kernel güncellemesi yaptım, güncelleme başarılı bir şekilde bitti ama sonrasında yazdığım komutlara cevap olarak "Segmentation fault" vermeye başladı. Reboot attıktan sonra hiç açılmaz oldu, sunucu OVH'de bulunuyor ve KVM maalesef yok sadece rescue moduna alabiliyorum.
Rescue modunda serverin / ve /home dizinleri mount edebiliyorum, dosyalarına ulaşabiliyorum ama chroot komutunu kullandığımda da "Segmentation fault" hatası veriyor.
Önceden libc ile alakalı bir problem yaşamıştım, yüksek ihtimalle bu yüzden hata veriyor olabilir.
