Hello,
please do you know any clever ways to check hard drives in Linux and discover its health/status/possible errors?
So far i found command:
smartctl -a /dev/sda
Example output: (takes around 15 seconds?)
[root@* ~]# smartctl -a /dev/sda
smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.18-371.3.1.el5.028stab110.1] (local build)

SMART Error Log Version: 1

SMART Self-test log structure revision number 1
No self-tests have been logged. [To run self-tests, use: smartctl -t]
SMART Selective self-test log data structure revision number 1
SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS
1 0 0 Not_testing
2 0 0 Not_testing
3 0 0 Not_testing
4 0 0 Not_testing
5 0 0 Not_testing
Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
To discover what particular values mean one can open this page and use Ctrl+F - https://en.wikipedia.org/wiki/Self-Monitoring,_Analysis,_and_Reporting_Technology#Kno wn_ATA_S.M.A.R.T._attributes
Legend/Explanations:
pre-fail - means that certain attribute is at or below manufactures expectations.
Old_age - describing a parameter type for some of the named attributes, which indicates it is expected to change with age; Old_Age is a definition of the SW been used
Reallocated_Sector_Ct - count of bad sectors, so if this value is high, it can be warning sign
Throughput_Performance - If the value of this attribute is decreasing there is a high probability that there is a problem with the disk.
Quick test with output:
smartctl -t short /dev/sda;echo "----- Sleeping 2 minutes -----";sleep 120;smartctl -a /dev/sda
Automatic checking & mail when HDD fails:
A)
1. open: vi /etc/smartd.conf
2. find first line with "@" (/@ + Enter) and change to your email and uncomment (remove #), then save (:wq + enter)
B)
modiffy your email and run command (on your risk):
find /etc -name 'smartd.conf' -type f -print0 | xargs -0 sed -i 's|#/dev/hdc -a -I 194 -W 4,45,55 -R 5 -m [email protected]|/dev/hdc -a -I 194 -W 4,45,55 -R 5 -m [email protected]|g'
this smartd.conf based check i did not veriffied that works /dev/hds dont exist
