Question

我创建了一个具有8GB根卷的AWS EC2 Linux实例。然后我将EBS音量增加到9GB，然后进入完成状态。它的体积很小，所以调整大小需要几分钟才能完成。

现在，我尝试使用提到的here指令调整卷大小后扩展linux文件系统。但是，我收到以下错误消息。我尝试了两次，整个过程。但它完全一样。

import csv
import re
from robobrowser import RoboBrowser
import time

def rechCadastre(data,result):
    time.sleep(0.01)
    form=browser.get_form(id="rech")
    repetition = ''
    if data[2]!='':
        repetition = data[2][0]
    param={'numeroVoie':data[1],'nomVoie':data[0],'ville':data[3], 'indiceRepetition':repetition}
    for x in iter(param):
        form[x]=param[x]
    time.sleep(0.01)
    browser.submit_form(form)
    success = browser.select('#onglet')
    if not success:
        result += "NS,NS"
    else:   
        answer = browser.select('.nomcol')[0]
        parcelle= re.split('(\W+)',re.search("Parcelle n\W [0-9]{1,4}",answer.text).group(0))[4]
        feuille = re.split('(\W+)',re.search("Feuille [0-9]{1,4} [A-Z]{1,4}",answer.text).group(0))[4]
        result += feuille+","+parcelle
    browser.back()
    return result


data = []
url = "https://www.cadastre.gouv.fr/scpc/accueil.do"
browser = RoboBrowser()
browser.open(url)

infile = open("treated.csv",'rb')
reader=csv.reader(infile)
for row in reader:
    data.append(row)

#compt=0
for data_point in data: 
#   if compt == 20:
#       break   
#   data_point = data[i]
    result = data_point[0] + "," + data_point[1] + "," + data_point[2] + "," + data_point[3] + ",,"
    nd = data_point[0] == "#N/D"
    rep = (data_point[2] == '') or (data_point[2] == 'BIS') or (data_point[2] == 'TER') or (data_point[2] == 'QUATER') and (data_point[2] == 'B')
    acceptable = rep and (not nd)
    if acceptable:
        result = rechCadastre(data_point,result)
    print result 
#   compt += 1

有人可以帮助我吗？

只需重启实例，因为它会在启动时自动调整根文件系统的大小。

我自己尝试过。以下是8GB卷的实例：

[ec2-user@ip-172-31-15-216 ~]$ lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   8G  0 disk 
└─xvda1 202:1    0   8G  0 part /

[ec2-user@ip-172-31-15-216 ~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        236M   56K  236M   1% /dev
tmpfs           246M     0  246M   0% /dev/shm
/dev/xvda1      7.8G  985M  6.7G  13% /

修改EBS卷后：

[ec2-user@ip-172-31-15-216 ~]$ lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   9G  0 disk 
└─xvda1 202:1    0   8G  0 part /

[ec2-user@ip-172-31-15-216 ~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        236M   56K  236M   1% /dev
tmpfs           246M     0  246M   0% /dev/shm
/dev/xvda1      7.8G  985M  6.7G  13% /

重启后：

[ec2-user@ip-172-31-15-216 ~]$ lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   9G  0 disk 
└─xvda1 202:1    0   9G  0 part /

[ec2-user@ip-172-31-15-216 ~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        236M   56K  236M   1% /dev
tmpfs           246M     0  246M   0% /dev/shm
/dev/xvda1      8.8G  984M  7.7G  12% /

# http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/storage_expand_partition.html
# Before goging to do this, detach and attach the root volume to anothe instance
# Note:
#   1) Before detach the volume, please make a note of device name which going to
#      detch from the machine, why because we should mention same name when attaching back, otherwise data will be lost
#   2)

# Identifying device name which we want to expand
lsblk

# Running parted command on the device
sudo parted /dev/xvdf

# Changing the parted units of measure to sectors.
unit s

# Run the print command to list the partitions on the device
print
# if it shows warning, chose fix

# Delete the partition entry for the partition using the number (1) from the previous step
rm 1 # number 1 will change based the partition we want to delete

# Create a new partition that extends to the end of the volume
mkpart Linux 4096s 100%

# Run the print command again to verify your partition
print

# Check to see that any flags that were present earlier are still
# present for the partition that you expanded. In some cases the boot
# flag may be lost. If a flag was dropped from the partition when it was expanded,
# add the flag with the following command, substituting your partition number and the flag name.
# For example, the following command adds the boot flag to partition 1
set 1 boot on

#Run the quit command to exit parted.
quit

# verfiying the device
sudo e2fsck -f /dev/xvdf1
