sdb1 partition /u01 alanına mount edilmiş durumda /u01 alanını genişletme ihtiyacı olduğunda, neler yapmalıyız, onu anlatmaya çalışacağım, öncelikle sanallaştırma ortamı kullanıyorsak sdb diskini extend etmemiz gerekecek. Burada biz extend işlemini yaptık ve aşağıdaki gibi disk alanımız büyüttük şimdi partition extend etmeye geldi.
~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 64G 0 disk
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 63G 0 part
├─ol_bfmnd1-root 252:0 0 43G 0 lvm /
└─ol_bfmnd1-home 252:1 0 20G 0 lvm /home
sdb 8:16 0 15G 0 disk
└─sdb1 8:17 0 10G 0 part /u01
sr0 11:0 1 10G 0 rom
Resize işlemini yapalım, doğrudan resize2fs komutunu verirsek henüz partitionın extend işleminden haberi olmadığı için hata verecektir;
# resize2fs /dev/sdb1 15G
resize2fs 1.45.6 (20-Mar-2020)
The containing partition (or device) is only 2621184 (4k) blocks.
You requested a new size of 3932160 blocks.
Parted ile partitionı extend edip sonrasında resize yapmalıyız;
# parted /dev/sdb
