    Halo,

    Minta bantuannya, dedicated server tiba-tiba crash, dan setelah reboot semua file system jadi read-only.

    Jul 24 06:16:36 server kernel: sd 0:0:0:0: [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
    Jul 24 06:16:36 server kernel: sd 0:0:0:0: [sda] Sense Key : Aborted Command [current] [descriptor]
    Jul 24 06:16:36 server kernel: sd 0:0:0:0: [sda] Add. Sense: No additional sense information
    Jul 24 06:16:36 server kernel: sd 0:0:0:0: [sda] CDB: Write(10): 2a 00 21 91 b3 10 00 01 78 00
    Jul 24 06:16:37 server kernel: Aborting journal on device sda8-8.
    Jul 24 06:16:37 server kernel: EXT4-fs error (device sda8): ext4_journal_start_sb:
    Jul 24 06:16:37 server kernel: EXT4-fs error (device sda8): ext4_journal_start_sb: Detected aborted journal
    Jul 24 06:16:37 server kernel: EXT4-fs (sda8): Remounting filesystem read-only
    Jul 24 06:16:37 server kernel: EXT4-fs (sda8): delayed block allocation failed for inode 12329117 at logical offset 0 with max blocks 7 with error -30
    Jul 24 06:16:37 server kernel: EXT4-fs (sda8): ext4_da_writepages: jbd2_start: 992 pages, ino 12329117; err -30

    Saya coba fsck /dev/sda8 tidak bisa di umount karena busy, kalau saya matikan prosesnya saya otomatis log out dari SSH.

    Sebelum coba di unmount coba masnya cek apakah ada proses yang jalan yang menggunakan partisi tersebut:

    lsof | grep sda8

    Kalau semisal ga ada, mungkin lebih bagusnya untuk fsck ini di single mode.

    sda8 ada proses dari root, setelah saya kill, malah terlogout. Cuma sda1 dan sda2 yang bisa saya umount dan fsck, sisanya tidak bisa karena ada proses dan tidak bisa di kill.

    Cara jalankan single mode di SSH?

    kalau layanan yang mas gunakan ada KVM-IP nya seharusnya bisa, mungkin bisa ditanyakan ke provider yang dipakai untuk detail opsi tsb.

    sulit mas penanganan recovery/perbaikan dedicated server yg bermasalah ke soal storage/file system tanpa ada ipmi/kvmoip,
    walau bisa dicoba dulu dengan mounting livecd/rescue cd, krn sistem rescue biasanya disediakan di panel dedicated yg nggak ada ipmi/kvmoipnya.

    kalau nggak ada keduanya (sistem rescue atau ipmi), mau ga mau mungkin install ulang solusinya atau keluar duit lagi untuk remotehand.

    ipmi juga jadi fitur penting untuk reinstall os tanpa harus menghapus partisi tempat menyimpan data. krn kalau one-click install/install os via template biasanya ada proses repartisi yg menghapus semua data-data.
